These envelopes have been great for shipping our sports cards through eBay's standard envelope services. A little pricey but they seem to keep the cards well protected. Also these are just the right size where you could ship 2 side by side and keep the envelope flat enough to not have issues with the Post office!

I buy and sell sports and non-sports cards. For most purchases, I use bubble mailers. If there's only one or two cards, I use these. I know that they'll get there safely with these! They're perfect as semi-rigid mailers. They are flexible enough that they still go through the letter sorter with no problems, but rigid enough that they protect the card and don't bend. I've seen others that get sent through the letter sorter that get crushed, break, or bend. They're super well made, the adhesive is great and actually sticks, they're durable, and they are reliable! Highly recommend.

great flat mailers, very rigid and have ordered them several times, the larger sizes however are not very rigid even though the thickness is the same, it has to do with the overall size so plan to order cardboard stiffeners if you are shipping artwork or anything that you dont want to bend in anything over the 6.5 x 4.5 mailers. highly recommended at the size reviewed.
