Here we have a package of 50 soft, crystal clear, plastic ATC sleeves for preserving your artwork. These Artist Trading Card sleeves are open at one end, so you can easily slide your ATC inside. There is no flap and no adhesive on the sleeve so that your ATC is protected to let your artwork shine through. The sleeves measure 2 5/8 inches X 3 5/8 inches, and are acid-free and archival safe. Again, there is 50 sleeves per package, but larger quanitites are available.
