What size is a #5 bubble mailer?

This one measures 10.5 by 15 inches, plus a 1.5-inch flap for sealing. That fits books, folded apparel and small boxed items.

Are these mailers padded?

Yes. Each envelope has a bubble-lined interior under a kraft paper outer, so contents get light cushioning.

The kraft paper surface takes marker, tape and adhesive labels directly.

The paper outer resists brief damp but is not waterproof. Use a poly mailer or extra wrap for wet-weather shipping.

The pack contains 100 mailers of this size.

Only lightly fragile items. The bubble layer is thin, so glass and electronics need a box or extra wrap.
