The guide

Each step in the order you'll need it.

01

Card sellers who reach for team bags

Team bags suit you if you ship toploaded cards, from one Charizard a month on eBay to forty hits sealed after a Whatnot break. A 100 pack at $5 to $10 lasts most part-time sellers a season.

They also work as a lot bag. On eBay and TikTok Shop, drop a stack of 20 to 30 sleeved commons in one, seal it and label the lot.

02

Resealable strip, inner size and clear plastic

Choose a resealable strip on the flap, so you or the buyer can open and close the bag without tearing it. Plain fold-over bags work but slip open in transit.

The bag should fit a standard 3 × 4 in toploader with a little room to seal. Thicker toploaders for patch cards may need a larger bag, so compare the listed inner size with your holders.

Acid-free clear polypropylene keeps the card visible in photos and avoids the cloudy look some cheap plastics take on.

03

Sealing toploaders without tape

Slide the loaded toploader in open end first, so the bag's closed bottom covers the toploader opening. Peel the strip and press the flap down from the middle outward.

Leave a small tab on one side of the flap unpressed so the buyer can lift it with a fingernail. The bagged card then goes into a rigid mailer, ready for its label.

04

Penny sleeves, zip-top bags and toploaders

Penny sleeves, 1,000 pack, are the fallback and the layer inside. A sleeve does a different job, so a card you ship on its own needs both.

For thicker stacks or graded cards, 4 × 6 in zip-top bags take bulkier items and work for sealed booster packs as well as card lots.

35pt toploaders, 100 pack, are the rigid holder the team bag closes over. Order the two together so the packing desk has both.

05

Holding sold hits between shows

Between shows, keep sold-but-unpaid hits in labeled team bags with the buyer's username on a sticky note inside. The note stays put and the card stays sealed until you pack it.

A 100 pack works out at roughly 5 to 10 cents a bag, so you can bag each hit as you pull it on stream and keep packaging cost to a few cents per card.

Common mistakes

Each one costs you money or reviews, and each has a fix.

  • Put the open end of the toploader in first. Closed end first leaves its opening exposed at the flap.
  • A fully pressed adhesive strip makes the bag hard to open; leave a small tab loose at one corner.
  • Thick patch holders split the seams of bags sized for standard toploaders, so check the inner size before you order.
  • Once the adhesive has picked up dust, a reused bag gapes in transit. A fresh one costs pennies.

Questions

Straight answers to what sellers ask about this.

Do team bags stick to the card?

No. The adhesive strip sits on the flap and touches the bag, so the card or toploader inside stays clean.

Can I use team bags without a toploader?

Yes, for low-value cards in stacks or sealed packs. A single valuable card needs a toploader inside to stop it bending.

How many toploaders fit in one team bag?

The usual size takes one standard toploader with room to seal. Two back to back will fit, with the seal under strain.

Are team bags waterproof?

Sealed, they keep out drizzle and condensation. They can't survive full immersion, so the outer mailer still does that job.
