Most mail doesn't need gold. It needs to look clean, land intact, and not make the recipient think you grabbed a bargain bin from the supermarket.
Cumberland's white strip seal pocket envelopes are the workhorse. 100gsm means your A4 documents sit flat inside without showing through. The 405 x 305mm size gives you breathing room for a cover letter, a few pages, and a receipt. The pocket keeps everything in place through the postal shuffle.
Box of 250. Print your batch, stuff them, seal, done. Your next 250 mailings are sorted before lunch.
