Works perfectly for my mailing
My coffee table book fits perfectly in the mailer. The material seems sturdy enough... how the books arrive at their destinations remains to be seen. If I get any complaints, I will update this review. I remain hopeful.

Not self-sealing
I really like the weight of these for shipping prints and calendars. I add a "please do not bend" sticker to the packaging for the postal workers. Overall a good product, and I bought 2 sizes: 9x12 and 13 x15. On the 13x15, the adhesive strips work fine. The adhesive strip does NOT work at all on the 9x12 size. Not even for a moment. I seal with packing tape. I bought 700+ of these for my online store and am not excited to add the extra step of having to seal each one.

I use these in my business, and they hold up well, haven't had any issues with adhesive lifting.
