6" x 6" Stay Flat Envelope
Compact square 6 x 6 rigid mailers sized for 5 x 5 square prints, jewelry, 7 inch vinyl and small flat collectibles. Peel and seal closure.
Description
The 6 x 6 stay flat envelope is the square format mailer for square format items: 5 x 5 prints, Instagram style square art, 7 inch vinyl 45s, small jewelry pieces, square invitations and craft samples. This 6 x 6 rigid mailer is made from 420 GSM heavy duty cardboard that refuses to crease, fold or buckle in transit, which matters when you are shipping flat collectibles or art that does not have a standard rectangular envelope option.
Inside, the 5.96 by 5.96 inch cavity holds 5 x 5 prints centered with margin on every side, fits 7 inch vinyl singles with protective sleeves intact, accommodates flat jewelry boxes, and gives small craft samples or square invitations a snug, protective fit. The 1.575 inch flap folds back for fast loading, and the self-adhesive seal strip closes each 6 x 6 square mailer in seconds without tape or scissors. The white, label-ready finish takes ink, stamps and shipping labels cleanly, and a built-in tear strip on the back gives recipients a clean, controlled opening.
This is the right size for square print artists shipping 5 x 5 wall art, Instagram printable shops, vinyl 45 sellers shipping 7 inch singles, jewelry brands mailing flat necklace and bracelet cards, craft sellers shipping small flat samples, and square invitation designers. Every pack ships with 200 free Do Not Bend stickers, the cardboard is fully recyclable, and bulk packs of 100 and 250 bring the per mailer cost down for businesses that ship the 6 x 6 stay flat envelope as a regular SKU in their square format fulfillment.
