Sizes run slightly small

The 6-inch bag fits a standard postcard tightly. If your card is thick or has a border, it might be a snug fit. Otherwise, good quality.

Perfect for my collection

These sleeves are exactly what I needed for my autographed sports cards. The adhesive seal is strong and the plastic is very clear.

Archival safe!

I was worried about acid damage, but these are labeled acid-free and look great. My vintage postcards are finally protected.

Great value pack

100 packs is a lot, but the price per unit is unbeatable. The clarity is excellent and shows off the autographs beautifully.

Easy to use

The self-sealing strip works perfectly every time. No need for tape or glue. Highly recommend for anyone selling cards online.

Good quality, slightly stiff

Great protection for postcards. The material is a bit stiffer than expected, which is good for durability but takes a moment to get used to.

Q: Are these sleeves suitable for graded slabs?

A: No, these are designed for raw cards and postcards. They will not fit rigid graded slabs.

Q: Do these come in mixed sizes or just one size per pack?

A: Each pack contains a single uniform size. Please select 4-inch, 5-inch, or 6-inch at checkout based on your needs.

Q: Is the plastic glossy or matte finish?

A: The finish is high-gloss to maximize the visual appeal of the photos and autographs inside.

Q: Will these protect against moisture?

A: Yes, once sealed, the polypropylene material provides a strong barrier against moisture and dust.

Q: Can I reopen the bag after sealing it?

A: While the adhesive is strong, you can carefully peel it open once or twice, but re-sealing effectiveness may decrease.
