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

Confidential mail that's been opened in transit is a conversation you don't want to have. These Cumberland retail strip seal envelopes give you a window face so the recipient's details are visible without opening, plus a security pattern that shows clearly if anyone's been inside.

80gsm paper. DL size, 110 x 220mm. Your invoices, contracts, or sensitive notices go in flat and come out untouched. The strip seal is quick – peel, press, sealed. No glue mess on your fingers while the phone rings.

A box of 1,000 (ten trays of a hundred) means you stock up once and stop thinking about it. Pull a tray, drop it in the mailroom, done.
