Frequently Asked Questions
Are rigid mailers safe for glossy photo prints?
Yes — rigid mailers prevent bending that can crease glossy prints. For extra surface protection, slide prints into a clear poly sleeve or add a thin backing board to avoid scratches from friction.
Do these mailers require extra tape to stay closed?
Most come with a peel-and-seal adhesive flap designed to hold, but some users report mixed adhesive strength on economy and even premium packs. For long shipments or heavy handling, adding a strip of packing tape is a simple way to ensure security.
Which size should I choose for greeting cards vs. photos?
Use compact 6.5 x 4.5-inch rigid mailers for standard greeting cards and 4x6 photos. Choose larger formats like 9 x 11.5 inches for letter-size prints, postcards that exceed 4x6, and small posters to avoid folding or trimming.
