The OEM Quality Park Redi-Strip Photo/Document Mailer is designed for securely mailing photos or important documents that should not be bent. Made of sturdy fiberboard, it features a convenient Redi-Strip closure that requires no moisture to seal; simply peel the strip off and fold the flap closed. The tear-string ensures easy opening, while the peel-off strip protects the adhesive from dust for a longer shelf life. Additionally, these mailers are made with a high percentage of recycled material.
