Good Price for the money. ### ⭐⭐⭐⭐⭐ Great for shipping orders! *by A***N on January 7, 2026* Great poly mailers. I use these for my Etsy shop and they get the job done. High quality materials, keeps contents safe and dry. Sealer glue works well but I still add extra tape, just in case. Thick plastic, great size for smaller items.
