  • Very good mailer
Size: 12 3/4 x 15 Pattern Name: Mailer
These are sturdy, as sturdy as you could expect from a stiff envelope. The flap adhesive is very strong - I had to open one up and the adhesive tore the cardboard so I can't imagine these opening up in transit. Will buy again.

  • Great for shipping art prints
Size: 6 x 8 Pattern Name: Mailer
I use these to ship fine art prints and they are perfect. I love how ridged they are, nice clean white packaging to add my own branding to. Adhesive holds well. Seem durable. I do add a piece of cardboard in with each print for additional rigidity.

  • Just what I needed.
Size: 9 x 11 1/2 Pattern Name: Mailer
I use these to ship license plates. They are strong enough to protect the license plate but light enough to keep shipping low.

  • Perfect for my needs
Size: 9 x 11 1/2 Pattern Name: Mailer
These hold my 310 page 6”x9” books perfectly and give good protection. So far I haven’t had one book damaged after hundreds of orders. The adhesion is very strong too. Great product and price.

  • Works perfectly for my mailing
Size: 12 3/4 x 15 Pattern Name: Mailer
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
Size: 9 3/4 x 12 1/4 Pattern Name: Mailer
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. ... show more
