Cumberland Strip Seal Post Code Envelope 80gsm DL 110 x 220mm White – Box of 1,000 (10 x 100)

Your invoices and letters deserve better than flimsy envelopes that burst open half a block from the letterbox. These Cumberland strip seal post code envelopes are 80gsm – thick enough to shrug off a wet Tuesday in the post van, thin enough to slip through a standard Australian post slot without jamming.

DL size, 110 x 220mm. Fold your A4 letter in half and it drops right in. The strip seal means you peel, press, done. No glue, no waiting for it to dry while the queue behind you grows.

A box of 1,000 keeps your mailroom or home office stocked for months. Ten trays of a hundred, so you pull one tray at a time and the rest stay flat and ready.
