Whether you're sending one as a gift or running a small resale business, the wrong packaging or carrier choice can leave your plush compressed, damp, or late. Here's everything you need to know to ship Squishmallows safely and affordably.

Key Takeaways
-
Match packaging to size: Poly mailers work for Squishmallows 8 inches and under; anything larger needs a corrugated box.
-
Vacuum sealing compresses — not permanently: Most Squishmallows return to full shape within 24–72 hours of being unsealed, but always make sure the plush is completely dry before sealing.
-
USPS Flat Rate boxes are exempt from dimensional-weight pricing, making them a smart, cost-saving option for bulkier Squishmallows.
-
Carrier rates increased in 2026 — USPS Priority Mail retail rates rose 6.6% effective January 18, 2026, but commercial shipping platforms offer discounts that offset this.
How To Prepare Your Squishmallow for Shipping
The first thing you should do is prepare the Squishmallow for shipping. Ensure you have the correct order and check if the tags remain intact. Also, it would pay to check the Squishmallow for tears or smudges to prevent unnecessary returns and exchanges.
If you can, take a photo or a video of the items along with the waybill before packing and sending them to the recipient. This step is especially important for resellers on Poshmark, Mercari, or eBay — photo documentation is your best protection against "item not as described" disputes on secondary market platforms.

How To Pack Squishmallows for Shipping
Choosing the right packaging protects the Squishmallow's shape, keeps moisture out, and keeps your shipping costs in check. Here's a breakdown of the most common options.
Vacuum Sealing
Vacuum sealing is one of the most popular methods for shipping large Squishmallows. It significantly reduces package volume, which can lower dimensional weight charges with UPS and FedEx.
A few important caveats before you seal:
-
The plush must be completely dry first. Any trapped moisture can cause mold or odors during transit — even a slightly damp Squishmallow sealed in an airtight bag is a problem.
-
Fluffiness will return. Most Squishmallows recover their shape within 24–72 hours after being unsealed and gently fluffed.
-
Avoid vacuum sealing rare or vintage Squishmallows. Older seams can be stressed by pressure, which could damage a collectible you're trying to protect.
-
Match the bag size to the Squishmallow. A common mistake is buying the wrong bag size — measure first.
For occasional shippers who don't own a vacuum sealer, hand-pump style vacuum bags are a popular and affordable alternative. They work with the same bag types and don't require a machine.

Ziplock Bags or Trash Bags
If vacuum sealing seems like overkill for a smaller or lower-value Squishmallow, a large ziplock or trash bag can provide basic moisture protection during transit. This method won't compress the plush, so you'll still need appropriate outer packaging to prevent shape distortion.
Corrugated Boxes
For medium to jumbo Squishmallows (12 inches and up), a corrugated box is the most reliable outer packaging. Line the interior with bubble wrap and use packing peanuts or air pillows to fill any empty space — internal movement during transit causes the most preventable damage.
You can reuse boxes from Amazon or other shipments, as long as the box is the right size (aim for about 2 inches of padding space around the Squishmallow), is structurally sound, and has no old shipping labels visible.
Free tip: USPS Priority Mail flat rate boxes are available at no cost at any post office or through USPS.com. They come in multiple sizes and are exempt from dimensional weight pricing — a real advantage for bulky plush shipments.
Poly Mailers
Using a poly mailer is a good option for small Squishmallows — specifically those 8 inches and under. If the Squishmallow doesn't fit without forcing, do not squeeze it in. Forcing a plush into an undersized poly mailer risks tearing the mailer and permanently distorting the Squishmallow's shape.
For a little extra peace of mind, wrapping the plush in bubble wrap before placing it inside adds impact protection.
Bubble Mailers
Another option is a water and tear-resistant bubble mailer. An opaque one is recommended so the contents aren't visible from outside. Wrapping the Squishmallow in water-resistant packaging assures both you and the recipient that the item won't be damaged in transit.

How To Choose a Carrier for Squishmallows
With carrier rates increasing across the board in 2026, choosing the right shipping service matters more than ever. USPS raised Priority Mail retail rates by 6.6% effective January 18, 2026 — though commercial shipping platforms like Stamps.com and ShipStation offer discounted rates that can offset this increase.
Here's a breakdown of the main options:
USPS Priority Mail
USPS Priority Mail remains the most popular choice for shipping Squishmallows. You can enjoy delivery in as little as 1–3 business days, and the flat-rate boxes — available free from USPS — are among the best cost-control tools.
Flat Rate boxes are exempt from dimensional weight pricing, making them especially useful for medium- to large-sized Squishmallows that would otherwise incur DIM surcharges. Priority Mail also includes $100 of default insurance coverage — a meaningful benefit if you're shipping a Squishmallow worth more than shipping basics.
USPS Ground Advantage
USPS Ground Advantage is the budget-friendly option that most shipping guides overlook. It replaced First Class Package Service and offers full tracking with delivery typically in 2–5 business days. For non-time-sensitive shipments or lightweight Squishmallows, it's often significantly cheaper than Priority Mail while still providing reliable service.
If you're shipping a smaller Squishmallow and speed isn't critical, Ground Advantage is worth comparing before defaulting to Priority Mail.
FedEx
FedEx is a strong option for shipping Squishmallows to international destinations, with service to a wide range of countries worldwide. They also offer reliable domestic ground shipping for larger packages. For high-value Squishmallows, FedEx's declared value coverage provides additional protection beyond basic carrier liability.
UPS
UPS is a solid choice for domestic ground shipping, particularly for larger or heavier Squishmallows, where negotiated commercial rates can reduce costs. Like FedEx, UPS uses dimensional weight pricing for larger packages, which is another reason to consider USPS Flat Rate boxes for bulkier shipments.
What Is the Cheapest Way To Ship a Squishmallow?
The cheapest way to ship a Squishmallow depends on its size, weight, and how fast it needs to arrive. As a general rule:
-
Small Squishmallows (8" and under): USPS Ground Advantage in a poly mailer is typically the most affordable option with tracking.
-
Medium Squishmallows (12"–16"): USPS Medium Flat Rate Box often beats weight-based pricing for coast-to-coast shipments.
-
Large and jumbo Squishmallows (20"–24"): Vacuum-seal to compress, then compare the USPS Large Flat Rate Box against UPS and FedEx Ground rates using their online calculators.
The farther the destination and the faster the turnaround time, the higher the cost. Commercial shipping platforms consistently offer lower rates than walking into a post office — if you ship regularly, an account with a shipping aggregator is worth setting up.
FAQs
Can vacuum sealing damage a Squishmallow?
For most Squishmallows, vacuum sealing is safe as a temporary shipping method. The plush will be compressed but should recover its shape within 24–72 hours once unsealed and gently fluffed. This technique is commonly used when shipping plush collectibles like squishmallows, especially when space in the box is limited. The main risks are trapping moisture (which can cause mold — always ensure the plush is dry before sealing) and potential seam stress on older or rare Squishmallows with weakened stitching. When used correctly, it can help ensure the safe delivery of these soft and often delicate items.
What size box do I need to ship a Squishmallow?
Match the box to the Squishmallow size, leaving about 2 inches of padding on all sides. For most 12"–16" Squishmallows, a USPS Medium Flat Rate Box works well. For larger plushies, including a giant squishmallow, a USPS Large Flat Rate Box is a good starting point — vacuum-sealing the plush first will help it fit more easily and enable effective shipping without excessive box size.
Should I add shipping insurance for a Squishmallow?
USPS Priority Mail includes $100 of default coverage. For Squishmallows valued above that — rare and limited editions can fetch significantly more once sold on collector marketplaces — it's worth purchasing additional insurance. The cost is modest compared to the risk of an uninsured loss on a high-value collectible. For many collectors and online sellers, protecting valuable plush toys during transit is essential.
Can I reuse Amazon or retail boxes for shipping Plush Toys?
Yes, as long as the box is structurally sound, the right size (about 2 inches of padding clearance around the plush), and has no old shipping labels or markings that could confuse carriers. Cover or remove any previous labels before applying your new shipping label. Reusing sturdy boxes is often the best way to reduce packaging waste while still protecting items that bring comfort to collectors and fans.
What is USPS Ground Advantage?
USPS Ground Advantage replaced First Class Package Service in 2023 and is now USPS's primary budget ground shipping option. It includes tracking, typically delivers in 2–5 business days, and is available for packages up to 70 pounds. For casual shippers sending lightweight Squishmallows without a tight delivery deadline, it's often the most cost-effective USPS option.
How much does it cost to ship a Squishmallow?
It depends on the courier you are planning to use, the service you want to avail of, and the destination of your parcel. The farther the place and the shorter the turnaround time is (e.g., same-day delivery), the higher the shipping costs would be. But where can you buy Squishmallows?
