Mead Envelopes, Press-It Seal-It, 9" x 12", Self Adhesive, Office Pack, Brown Kraft, 75-Pack Without having to moisten the seal, or endure the foul envelope aftertaste, the self-adhesive seal instantly closes. Mead self-adhesive kraft envelopes are perfect for general correspondence that is too large to fit in a standard envelope or shouldn't be folded. No more moisteners, gummed flaps, tape, or glue. Just pull back the protective tape from the flap of each envelope and close it down for a secure seal. Address them by hand or use computer labels.
