These Quality Park 9" x 12" catalog envelopes are made from 100% recycled content with 40% post-consumer content. Our 24 lb kraft brown envelopes have a Redi-Strip closure. Just peel and press for an instant seal, no moisture required. Redi-Strip envelopes are the perfect mailroom update for concerns about surface germs in the workplace. Skip the yuck, stay safe and save time with every mailing. Plus, the peelable paper strips protect your adhesive from dust so envelopes last longer in storage. Brown kraft paper has longer, stronger fibers than wove paper, which makes for a durable envelope with natural charm. Center seam construction gives added strength for heavy contents. Our kraft brown envelope is ideal for hand addressed or labeled letters, though not recommended for printing due to the natural color and texture of the paper. This opaque kraft envelope will protect private contents and lend a sophisticated, rustic touch to your communications. Don't settle for bulky, stuffed white #10 envelopes with double-folded inserts or more expensive oversized flats. Our large envelope can store letter-sized papers flat. This 9 x 12 is the perfect compromise for cost-effective, professional-looking mailings with a little room to spare. Ideal for photos, art prints, certificates, registration materials or any letter or oversized papers you prefer to send flat without creases. Order boxes ahead for special projects. 100 Per box.
