Need to mail something quickly? Grab a Quick Ship Mailer and send it on its way! The Quick Ship Mailer has positive lock closure to assure it will remain closed while in transit. These newly redesigned mailers are solid white - no printed labels - which makes them suitable for many uses other than mailing: replacement boxes for games and puzzles, collections storage, gift giving, document archiving, party favors, or small commercial packaging to name a few. Use permanent Sharpie® Marking Pens to ensure the address on your mailer doesn't smear or smudge.
