4 x 6 3/8 Kraft Clasp Envelopes 1000/Case

These 28 lb. woven kraft envelopes come with reinforced metal clasps, allowing for multiple uses. To seal them securely and permanently, simply moisten the gummed flap and press it closed.

Using these envelopes is easy. If you want to reuse them, the reinforced metal clasps are there for you. Just open and close the clasp as needed. For a permanent seal, find a damp cloth or dip your finger in water and moisten the gummed flap. Then press it firmly shut. When it comes to storage, keep them in a dry place to prevent the gummed flap from sticking prematurely or the paper from getting damaged. If the envelopes get dirty, you can gently wipe them with a dry cloth. Avoid getting them wet other than when you're sealing the flap, as excessive moisture can weaken the paper and the clasps.
