Jiffy Rigi Bag Shipping Rigid Mailers, Case of 200, Recycled Bend Free Puncture Proof Fiberboard Mailing Envelope, #4-9.5" x 14.5", Kraft

great product and great service

I like this product because the package is strong. There is no way to damage the 10" x 12" x 1/4" book that is placed in it. The seal on the package is almost impossible to break--won't open during shipment.

Very good quality, I keep re-ordering!

These work great, will be buying again

I was pleased to be able to buy this product in a large quantity. The mailer bags are sturdy and work well for mailing calendars.

Honestly not sure how other reviewers are giving this 5 stars. I currently ship comics using a stay flat mailer with a 1/8 thick cardboard insert. This mailer absolutely cannot be used reliably protect the content from bending. It is filmsy and will bend. In addition, instead of regular self seal, it uses some kind of strange exposed glue that is not sticky at all, and makes putting item inside the envelope difficult as the glue will stick to the item as you put it in.i dont think i will ever find a rigid mailer that can safely ship comics with no bending, will just have to continue to use envelop + cardboard insert combo.

Really like the rigidity and simple sealing of these!

They are envelopes.. they hold things
