All-purpose mailing envelopes offer a convenient solution to mailing larger items and ensuring confidentiality. Blue security tint keeps contents confidential while in the mail stream. Redi-Strip on the flap provides a clean, quick seal immediately upon contact. Simply peel off the adhesive strip and press to seal. The peel-off strip protects the adhesive from dust for a longer shelf life. When you want to avoid folding your document, these envelopes are the right choice. This 10" x 13" size will accommodate standard or oversized documents without folding. Bright-white stock gives mailings a professional look.
