No. 10 Treated Security Envelopes are made with a material that inhibits the growth of mold and mildew to protect your contents. Security tint with pattern makes it difficult to read the contents even when held up to light. Remove the easy-to-use, peelable paper strip and press for a permanent seal.
Orders ship directly from national U.S. distribution centers, so a multi-item order may arrive in more than one shipment. Shipping is charged at checkout by order value. Bulky and freight items are priced separately.
