This product is used in a law office for mailings which are too thick for a regular envelope but do not need to go in a large mailing envelope or box. It holds approximately 30-40 pages securely and was economically priced for the budget concious office.
Used for mailing letters/documents which I do not want to fold. Side opening makes it easy to put the documents in. However you have apply a tape to close the envelope to ensure that the seal does not come off during transit as most seals do not hold firmly.
