Simplify your mailings with these Staples envelopes. The white envelopes are just the right size for everyday mailing at home or in the office and feature peel-and-seal closures for a smoother look without mess. The sturdy envelopes offer a professional feel for business documents, and the extra capacity box keeps the supply closet stocked for longer.

No Mess
These envelopes feature a self-sealing square flap closure for a crisp, professional look without any wrinkles. The adhesive also spares you from having to lick the seal or use sponges, so you can seal large numbers of envelopes faster without any mess. Just peel and seal; because the easy-close envelopes require no licking, there are never any missed spots or poorly sealed letters, so you have better security with each mailing.

Everyday Mailing
With interior dimensions of 4 1/8 by 9 1/2 inches, these envelopes are just right size for most mailing purposes, including letters, invoices, brochures and letter- and legal-sized papers. Each 24-pound paper stock envelope is substantial enough for important business documents and clearly shows both handwriting and pre-printed labels, so you can use the product at work or home.

Extra Capacity
Each box contains 500 envelopes, so you always have enough on hand. The extra-large box helps your office avoid extra trips to the stationers and saves you money in the long run.
