6.5" x 4.5" Stay Flat Envelope
Compact 6.5 x 4.5 rigid mailers sized for 4 x 6 photo prints, postcards and small trading cards. Peel and seal closure closes in seconds.
Description
The 6.5 x 4.5 stay flat envelope is the smallest rigid mailer in the Flextribe range, sized for the most common small flat shipments: 4 x 6 photo prints, postcards, business cards in bulk, ATC art cards and standard trading cards. This 6.5 x 4.5 rigid mailer is made from 420 GSM heavy duty cardboard that holds its shape against carrier handling, weather and machine sorting, even at this compact size where bending pressure is concentrated.
Inside, the 6.46 by 4.46 inch landscape cavity is sized for 4 x 6 prints with a comfortable margin on each side, holds postcards securely without sliding, and fits standard trading cards, ATC artist trading cards and stacks of business cards. The 1.575 inch flap folds back enough for fast loading, and the self-adhesive seal strip closes each 6.5 x 4.5 stay flat envelope in seconds without tape or scissors. The white, label-ready finish takes ink, stamps and shipping labels cleanly, and the built-in tear strip on the back gives recipients a clean, controlled opening every time.
This is the right size for postcard sellers and vintage postcard collectors, photographers shipping 4 x 6 prints from family sessions and events, business card printers mailing samples to clients, ATC and small art card sellers, trading card sellers handling standard sized cards and stickers, and small Etsy sellers shipping postcard art. Every pack ships with 200 free Do Not Bend stickers, the cardboard is fully recyclable, and bulk packs of 100, 200 and 300 bring the per mailer cost down significantly for businesses that ship small flat items in high volume.
