These are #2 padded mailers with a bubble-lined interior and a self-sealing, tamper-evident flap. The outer measures 8.5 x 12 inches and the usable space is about 8.5 x 11 inches, so they hold letter-size prints, photos, planners and thin books flat with cushioning a plain envelope can't give. They ship 250 to a case, which suits regular sellers of flat goods rather than occasional shippers. Against poly mailers they add real padding; against boxes they save bulk and packing time, though they won't protect fragile or bulky items.

Rated 4.8 out of 5 across 34 ratings, buyers are largely satisfied with these mailers as a packing staple for flat orders.
This #2 bubble mailer measures 8.5 x 12 inches on the outside. The usable inside space is 8.5 x 11 inches, close to the size of a letter-size sheet with a little added room. It suits flat shipments such as prints, photos, stationery sets, planners, thin books, catalogs and certificate documents (with a stiff insert).
The mailer has a bubble-cushioned lining that absorbs everyday bumps and drops and helps limit scuffs and light creasing. The outer layer is water blocking, which helps keep packages clean in light rain, splashes and damp conditions. The film is rip-resistant to reduce tears at the edges and corners.
It closes with a self-sealing strip: peel, fold and press, with no tape needed. The seal is tamper-evident. The mailer is lightweight and stores flat, and it is recyclable.
