10 x 13 White Gummed Envelopes 500/Case

These 10 x 13 white envelopes come in a case of 500. Their flaps are heavily gummed, ensuring a tight and secure seal. They're crafted from sturdy 28 lb. paper stock, making them reliable for your mailing needs.

To use these envelopes, simply moisten the gummed flap with water or a damp sponge and press it down firmly to seal. When inserting items, make sure they fit comfortably without overstuffing to avoid tearing the envelope. Keep these envelopes in a dry place to prevent the gum from drying out or getting sticky. If the gum seems dry, you can gently remoisten it. Avoid exposing them to extreme temperatures or humidity as this could damage the paper.
