Swallow Brand "Special Selection Rubber Band" I found this while cleaning out my house. I think it's from the Showa or early Heisei era. It's in good condition considering its age. It's unclear if it's still usable. It could be a good addition to a package collection, or you could actually use it. Please understand that this is an old item before purchasing. Robust and Unrivaled, Quality First The "SWALLOW" and "Swallow Brand" logos can be seen on the package. Retro product Showa era Heisei era
