Sooper Strap is an 18" long strap that gently but firmly cuddles your roll material. Using memory metal and soft rubber, the Sooper Strap locks into a flat strap. Kink it and it snaps into a coil. It's suitable for rolls up to 4" in diameter. Keep your small rolls of print media, laminate, banner, paper, canvas, and fabric rolled neatly. Stop using damaging and annoying options such as paper clips, tape, and rubber bands.
