50 Pack Rigid Mailers 9.5x12.5 inch, Self Seal Photo Document Mailers Stay Flat White Cardboard Shipping Envelopes Photography Mailers for Document, Photos, Papers, Files, CD

I love these. I just upgraded in size slightly, because I ship papers and small baggies of product in these, and these mailers are perfect. At 9" long you cna fold a piece of typing paper in half and have it fit perfectly, and then I can stick a couple baggies of my product onto the receipt and it ships just great.The only thing I notice is they're more flexible than my last ones I got, which were a different brand. These are slightly more lightweight, and a little thinner.

Let’s take a moment to appreciate these 6"x8" self-seal envelopes, shall we? If envelopes had a fan club, I’d be the president, complete with a sash and a collection of stamps that I may or may not use.First off, the self-seal feature is a game-changer! Gone are the days of awkwardly licking envelopes like I’m preparing for a culinary disaster. Just peel and stick! It’s like they read my mind and knew I was never meant to be a “lick and seal” kind of person.The size? Perfect! It’s just the right amount of space for a card, a letter, or a sports card that I just sold on eBay. These envelopes have got my back. They’re durable enough to survive the postal system, which is saying something considering the journey they take.In conclusion, if you need envelopes that are reliable, easy to use, and make you feel like a professional sender of things, these 6"x8" self-seal wonders are for you. My life has been transformed from “envelope struggle” to “envelope champion!” Bravo to the geniuses behind these little packages of joy

The adhesive is strong.The cardboard is sturdy and semi rigid. Great for shipping trading cards and jump sized trading cards as well.

I use this to mail out trading cards and it works out great. Had no complaints from buyers. Rigid and good quality.

PERFECT FOR MY GREETING CARD COMPANY

I sell trading cards on ebay and they offer an economy shipping service for cards valued $20 and below and I've found that these mailers are the best packaging option for shipping within the guidelines of this shipping service. I'll save you those guideline details but these envelopes are good enough for professional use.However, understand that these mailers are not considered 'rigid,' but they are thick enough to offer protection to your item depending on how you ship. I place trading cards in top loaders and use masking or painters tape to secure the card at the center of a folded 8 1/2 x 11 piece of thick card stock which i cut down slightly to fit into these mailers. This ensures the cards i'm shipping do not move around and are protected from impacts at the corners during transit.I've probably orders these three times already and I swear by them.

This is a thin but very durable cardboard self-sealing mailer. I got the 4x6 because we ship collectable gaming cards. I like everything about these except that I must tape the self-sealing flap down with strong package tape, as it pops back up, and also ink smears when I write the address on the exterior. That too must be covered in packaging tape. Otherwise, this is an excellent protective mailer.

I bought these to sell collectable cards on ebay. They are 6x8 which fits the guidelines for ebay standard envelope shipments (under $20 collectable cards non graded). They have enough room for a standard shipping label and 2 do not bend stickers. I can easily ship a couple cards in a top loader or a booster pack while utilizing the cheaper ebay standard envelope shipping prices.
