24-lb White Wove, 100/Box QUA69117, Redi-Strip Closure, Security Tint and Pattern, 4-1/8" x 9-1/2", Quality Park #10 Self-Seal Security Envelopes

#ad
Quality Park #ad - Less yuck: we promise you won't miss licking envelopes or crumbly, drippy sponges; complete your mailings, no accessories required. Save time with self-stick: quality park #10 Security Envelopes have a strong peel & stick closure that helps you fly through mailings in record time.

An excellent value: bright white 24-lb paper makes an impression for business mailings and personal correspondence; get 100 4-1/8 x 9-1/2 inch envelopes. Enhanced security: offer the protection clients deserve; a security tint makes envelopes hard to see through; a security pattern scrambles the appearance of text. Store more, longer: reid-strip envelopes have a longer shelf-life thanks to the peel able strip that protects your adhesive from dust.
