3 1/2 x 6 1/2 Kraft Gummed Envelopes 5000/Case

These kraft envelopes feature heavily gummed flaps, ensuring a tight and secure seal. They're crafted from sturdy 28 lb. paper stock, providing durability for your important documents.

To use these envelopes, simply moisten the gummed flap and press it firmly to seal. Make sure to check that the flap is fully adhered for a secure closure. When inserting items, be careful not to overstuff as it might prevent a proper seal. Store these envelopes in a dry place to keep the gum on the flaps in good condition. Avoid exposing them to extreme heat or moisture, as this could affect the envelope's integrity and the gum's stickiness.
