6" x 8" Stay Flat Envelope

The 6 x 8 stay flat envelope is built for the small, high value flat items that absolutely cannot afford to bend in transit: graded trading cards, sports card slabs, 5 x 7 photo prints, 5 x 7 invitations, collectible postcards and small art prints. This 6 x 8 rigid mailer is made from 420 GSM heavy duty cardboard that holds its shape through carrier sorting machines and rough handling, which is the entire point when the contents inside are worth far more than the postage.

Inside, the 5.96 by 7.96 inch cavity is sized snugly so contents do not shift during transit. A graded PSA card sits centered without sliding. A 5 x 7 photo print fits with a comfortable border. A small invitation suite stays organized. The 1.575 inch flap folds back enough for fast loading and the self-adhesive seal strip closes each 6 x 8 stay flat envelope 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, careful opening that protects the contents.

This is the size trading card sellers reach for first: graded slabs, PSA cards, BGS cards, sports cards and Pokemon collectibles all ship flat and safe in a 6 x 8 rigid mailer. It is also the right pick for photographers mailing 5 x 7 prints, wedding stationers shipping 5 x 7 invitation samples, Etsy sellers shipping small art prints and pet portraits, and eBay resellers handling small flat collectibles. Every pack ships with 200 free Do Not Bend stickers, the cardboard is fully recyclable, and bulk packs of 125 and 280 bring the per mailer cost down significantly for high volume sellers.
