Order #10 Custom Security Envelopes and get free shipping! Use these envelopes to mail checks, invoices, statements, and more.
These standard business envelopes measure 4 1/8 by 9 1/2-inches in size, making them the ideal size to send out all standard sized letters and documents. Before inserting into the opening, fold your 8 1/2 x 11-inch sheets into thirds.
These #10 Custom Security Envelopes have a conventional, moisture-activated gum seal. Once the items are inserted, add moisture and press down firmly to seal. The security tint on the inside of the envelope will keep sensitive information confidential. All handwritten and printed text will be kept private.
