Columbian Security Tint Busines Envelopes, White, 500 / Box (Quantity)

These business envelopes are ideal. They provide the following: 1) Gum flap that will not come loose or can be readily peeled apart. After losing a personal check in mail using a self-stick envelope, I rely on gum flaps again. 2) Paper weight is 24 lb., which provides better quality than low cost 20 lb "tissue paper" envelopes. 3) White color outside and inked inside.
