You've got a batch of invoices, contracts, or client letters that need to land with some weight. Not flimsy, not generic. These Cumberland B4 envelopes in gold do that job. 100gsm stock sits firm in the hand, the strip-seal closure keeps contents tucked in, and the pocket opening on the short side means nothing slides out mid-transit. 250 per box, so a full week of mailings is covered before you think about restocking. Print your letterhead, drop the docs in, seal the strip, and post. Sorted
