Filler Pads for Magazine Mailer Boxes. 8-3/4 x 11-1/4".
200-lb-test corrugated cardboard.

I sell magazine and these and a padded mailer are all I need for quick and secure mailing.

Does the job

This makes shipping magazines very easy to do. Keeps them protected within a mailer.

Good product overall. Strong enough to insert in a rigid mailer with a sleeved art print, no extra padding and it ships undamaged. I wouldn't mind getting a slightly larger size to insert into the envelopes though.

This insert works great. It makes the rigid mailer stand up to any normal mailing. I have used them to ship all over the world.
