Description

Our A4 cardboard envelope pack of 20 contains twenty white all-board mailers, each 248 x 330mm, made from 350gsm coated board so documents and photos arrive flat. Each closes with a peel-and-seal strip and opens with a tear strip.

Also available: box of 100. All-board envelopes are stiff on both sides, so they protect better than board-backed envelopes with a paper front.
