Good quality, slightly small for larger items

The material feels durable and clear. They work perfectly for standard postage stamps, but if you have oversized commemorative sheets, check the dimensions first. Still a great buy.

Excellent protection

I use these for organizing my handmade greeting card embellishments as well as stamps. The OPP material is stiff enough to provide structure but flexible enough to slide items in easily.

Perfect for my stamp collection

These sleeves are exactly what I needed. They are crystal clear and the adhesive strip seals tightly without damaging the stamps. Great value for 500 pieces.

Decent but sticky residue on some

Most of the bags are fine, but about 10% of them had a bit too much adhesive on the strip which left a slight residue. Usable, but not perfect.

Best bulk option available

As a serious collector, going through sleeves quickly is normal. This 500-pack is the most cost-effective solution I've found that doesn't compromise on clarity or safety.

Fast shipping and great price

Arrived quickly with free shipping. The packs were well sealed. No issues with the adhesive failing on any of the bags I've used so far.

5 FAQ

Q: Do these come with individual backing cards?

A: No, this product includes only the protective OPP sleeves. Backing cards are sold separately if you need rigid support for your items.

Q: Can I reuse these bags if I open them carefully?

A: While the peel-and-seal strip is designed for secure closure, reusing them may reduce the adhesive effectiveness. For maximum protection, we recommend using a new sleeve for each item.

Q: Are these bags archival safe and acid-free?

A: Yes, our Mingtai PCCB OPP sleeves are made from acid-free materials, making them safe for long-term storage of your valuable stamps and paper goods.

Q: What are the exact dimensions of each sleeve?

A: Each sleeve measures approximately 2.5 inches by 3.5 inches, designed specifically for standard single stamps and small collectibles.

Q: Is the packaging recyclable?

A: The outer packaging is made from recyclable cardboard. The OPP sleeves themselves are plastic and should be disposed of according to your local plastic recycling guidelines.
