Staples Gummed Invitation Envelopes, 5 3/4" x 4 3/8", White, 100/Box (50310T/15601)

Mail correspondence with these white gummed-closure invitation envelopes. Each one has a heavily gummed flap that doesn't activate until moisture is applied, so the envelope doesn't seal shut until you're ready, while the 24-pound paper stock helps protect contents from ripping, punctures and water damage. These Staples gummed-closure invitation envelopes are bright white to contrast against dark text and labels, making them easy to read.
