1. Toploaders Are Non-Negotiable
Even for commons, a toploader is your first line of defense. Slide the card into a penny sleeve first (like socks before shoes), then into the toploader. Seal the top with painter’s tape or low-tack card-safe tape—never Scotch tape. Scotch tape is the enemy of clean removal and mint condition.
Ken’s Pro Tip: Add a pull tab to your tape for easy removal. Buyers notice the little things—and they remember who made it easy. Personally, I like using these low-tack tabs to seal the top loader.
2. Team Bags Keep It Tidy
Shipping multiple cards? Bundle them in a team bag. It prevents shifting, keeps everything clean, and looks professional. For high-value cards, toss in a corner protector or ding defender. It’s a subtle flex that says, “I’m a collector too.”
Ken’s Pro Tip: Branded team bags are a game-changer. They turn packaging into marketing—every buyer becomes a potential repeat.
3. Cardboard Sandwich = Card Fortress
For raw cards or bulk orders, sandwich them between two pieces of cardboard and tape the edges. Slide that into a bubble mailer or rigid envelope. It’s DIY armor—and buyers love it.
Disclaimer – I don’t like using a lot of cardboard so I use ding defenders. It’s not necessary, but I think it presents as cleaner and more professional shipping.
Ken’s Pro Tip: Buy bubble mailers and rigid envelopes in bulk on Amazon. It’s cheaper, faster, and scales with your store.
4. PWE vs. Bubble Mailer: Know the Line
I use these rigid envelopes even for cards under $20. They ship well and are usually thin enough to go through USPS scanning and machining. Plus, a 4×6 mailing label fits awesomely on these
Anything above that deserves a bubble mailer and a ding defender. It’s not just about protection—it’s about peace of mind.
Ken’s Pro Tip: If losing the card would sting, don’t risk it in a PWE. And if you’re doing volume, invest in a thermal label printer—it’ll save you hours.
5. Include a Thank You Note (Even If It’s Just 5 Words)
A quick “Thanks for your purchase!” scribbled on a sticky note humanizes the transaction. It builds loyalty and repeat buyers. You’re not just selling cardboard—you’re building a brand.
Ken’s Pro Tip: Print custom thank-you notes with your thermal printer. Tuck them inside team bags for a clean, branded touch.
6. Weigh It Before You Pay It
(and Use eBay Standard Envelope When You Can)
Guessing postage is a rookie mistake. Use a postal scale to avoid underpaying and angry buyers stuck with postage due. USPS loves precision—and so do your margins.
For raw cards under $20, eBay Standard Envelope is a game-changer:
- ✅ Tracking included
- ✅ Up to 3 oz
- ✅ Rates from $1.32 ( I always add another $1.00 for soft sleeve, top loader, and envelope. Don’t be afraid to recoup cost!)
- ✅ Seller protection if tracking shows delivery
Ken’s Pro Tip: Use a rigid envelope + team bag + toploader combo to meet eBay’s packaging guidelines. And don’t forget to weigh it—3 oz is generous, but extras add up fast.
7. Track It When It Matters
For anything over $20, add tracking. It’s worth the extra $1–2. Buyers feel safer, and you’ve got proof if things go sideways. eBay’s seller protection only kicks in if you can prove delivery.
Ken’s Pro Tip: Make sure your thermal printer supports USPS tracking barcodes. Most popular models do—and they print fast.
🧤 Bonus Tip: Ship Like You’d Want to Receive
Before sealing the package, ask yourself:
Would I be excited to open this?
If the answer’s yes, you’re doing it right.
Ken’s Pro Tip: Every package is a handshake. Make it count.
