Cumberland Strip Seal Secretive Envelope DL 110 x 220mm 80gsm White – Box of 500

You don't need another envelope that half-seals in transit or lets a curious hand read through the paper. You need one that stays shut and keeps your contents private until the intended recipient opens it. The Cumberland strip seal secretive envelope does exactly that. The secretive pattern blocks visibility through the paper, and the strip seal means once you press it down, it stays down. No re-taping, no flapping open in a mailbag.

Fits a standard A4 sheet folded to thirds. The 28 x 95mm window keeps the recipient's address visible without cracking the pack open. 80gsm white paper handles a typical letter, invoice, or report card without tearing or creasing.

Box of 500. Print your company logo or school emblem on it and you're set for a full term or a quarterly mailing run without running back to the shop mid-week
