Perfect For Standard Size Magazines !
I needed these for shipping my standard size magazines and comics. You can't beat the price. I run a small online business so I have to watch my costs. The price was fantastic! Very sturdy!

Good for signed documents, holds up to USPS handling.
Hefty cardboard, great glue strip. Keeps my signed documents safe, and extra safe with added slip of cardboard. Of the hundreds I have shipped, USPS only was able to "mangle" two of them. No complaints from my customers, no extra taping needed. Great product, made in the USA.

No more complaints
I ship over a hundred packages a year via UPS. I was getting complaints from clients that the envelopes that I was using were damaged on arrival so I started using these mailers. These things are virtually indestructible. Tape over glue on sealing flap gets hung up once in a while but not if you are careful. No more complaints.

Very good 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.

Serve My Mailing Purposes Just Fine
These are an excellent substitute for the mailers I used to use but became too expensive. These feel a little less sturdy but I haven't had any problems.
