Packaging Guidelines

Whatnot Support Whatnot Support

Safe shipping starts with the right box. We recommend choosing a sturdy box with about 2 inches of extra space on each side of the item. This will allow for plenty of room for padding.

It's important that you pack your collectibles safely before shipping to ensure they do not get damaged. If you do not follow the guidelines below, you may have to pay higher seller fees, or your selling privileges could be revoked.

Once an item sells on Whatnot, you must package the item as follows:

  • Wrap the item with a protective material before putting it in a box 
  • Please use a bubble mailer when shipping out cards to ensure the item doesn't get damaged. If you are shipping cards using First-Class Mail Letter Shipping, please review this article for packaging guidelines.
  • The box or bubble mailer must have enough room such that the item will not be easily crushed
  • For smaller collectibles in cardboard boxes we'd advise against using airbag protectors as they often crush the item
  • It's important that the box isn't overfilled with packing materials or the item can be squashed in transit. Be sure there's enough room that if you pushed the walls of the box in a bit, the item will not get crushed
  • Please do not write or include written or printed propaganda in your shipping box.

Packaging recommendations by category

Regular-sized Funko Pops

Guidelines for shipping a single regular-sized Funko:

  • Put your Funko Pop in a soft protector. Check out our exclusive discounts on protectors for Whatnot sellers!
  • Place bubble wrap around the protector
  • Ship the Funko Pop in an 8x6x6 Box
  • Fill large empty spaces in the box with scrunched-up newspaper, bags, or packing peanuts, but leave some room for the Funko Pop to breathe                  

Regular-sized Figpins

  • Place bubble wrap around the item
  • Ship in a sturdy 7x2x4 box
  • Fill large empty spaces in the box with scrunched-up bubble wrap, newspaper, bags or similar material 

Cards (General)

  • There must be an extra layer of protection on whatever is being shipped to prevent damage. Common packing items are cardboard squares, bubble wrap, or an extra bubble mailer.
  • There should never be empty space in the package or bubble mailer that would allow the contents to move around. Bubble wrap, packing peanuts, packing paper, or air pillows are required in the package to prevent the contents from moving around in transit.

Graded Cards

  • It is recommended that each slab is placed in a graded card sleeve or team bag to prevent scratching on the surface of the slab.

Raw Cards

  • Any card of significant value must be placed in a penny sleeve and a top loader. Toploaders and sleeves must be the proper size to match the card’s thickness.
  • It is required that all raw cards are placed in a team bag in order to prevent them from moving around in transit.
  • It is recommended that all cards, regardless of value, are placed in a penny sleeve.

Thick Raw Cards

  • For thick cards, it is recommended that the corner of the thick penny sleeve is cut in order to smoothly place the card inside without damaging corners. 
  • It is recommended to use painter's tape (not scotch tape) to seal the opening of the top loader to prevent the card from sliding out.
  • If a magnetic case (mag) is being used, make sure it is the right size. It is recommended to put a penny sleeve over the front of the card before sealing the mag to prevent surface damage.

Raw Comics

  • All comics must be shipped in a comic mailer or cardboard box, not a bubble mailer.
  • All single comics must be bagged & boarded, and comic lots need to be protected with either comic bags or larger plastic bags.
  • It is recommended that at least one piece of cardboard be used to stabilize comics shipped in a mailer.

Graded Comics (Slabs)

  • All slabbed comics must be wrapped in bubble wrap or placed in a large bubble mailer to prevent damage in transit.
  • All slabbed comics must ship in a cardboard box. Do not ship slabs in bubble mailers or polybags with bubble wrap. A slabbed comic wrapped in a couple of layers of bubble wrap will fit perfectly in Mailing Box 1095.

Sealed Wax

  • All sealed wax must be shipped in a box, not a bubble mailer. 
  • It is recommended that the sealed wax is wrapped in bubble wrap.

Estate Sales and Vintage Decor

  • Place bubble wrap and/or paper around each item.
  • Be sure to ship using a sturdy, sealed box.
  • Fill large empty spaces in the box with scrunched-up bubble wrap, newspaper, bags, or similar material.

Retro Games

  • Single, sturdy games less than $50 (e.g., cartridges, Sega clamshell cases, DVD or Blu-Ray style cases):
    • Place the item in a third-party, flexible protector for added protection, or utilize a disc envelope for loose disc sales.
    • For single items or multiple enveloped discs, weatherproof padded mailers are OK. Please provide cushioning material to prevent movement once the mailer is sealed.
    • For multiple items that won’t fit in a weatherproof padded mailer, utilize a box and a minimum of one inch of padding or bubble wrap.
      • *You should not hear any movement if you shake the box while holding it closed.
  • Single, fragile games more than $50 (e.g., Nintendo cardboard boxes, jewel cases):
    • Place the item in a third-party, flexible protector for added protection, or utilize a disc envelope for loose disc sales.
    • Utilize a box with a minimum of one inch of bubble wrap or padding.
      • You should not hear any movement when shaking the box.
  • Soft-boxed games (e.g. NE,S, SNES, and N64):
    • Ensure that there is no movement of the cartridge inside the box.
    • NES boxes should have a styrofoam block that inhibits movement.
    • SNES and N64 boxes should have trays for the cartridges to sit in that will help protect both the carts and the boxes while in transit, provided the trays are still in good shape.
