Your A4 printout won't fold neatly into a standard envelope, and you've had enough of documents arriving creased or half-torn. These Cumberland strip seal expandable envelopes take the guesswork out. The 150gsm body holds its shape under a full stack of paper, and the expandable gusset means you're not squeezing three pages into two. The strip seal locks shut properly — no flapping, no spilling on the counter at the post office. White finish, clean window face, and a subtle pattern that keeps your contents out of sight. Twenty-five to a pack, so you've got a run before you need to reorder
