SnakeSkin Wire-O is a binding wire that is packaged in a flexible plastic "Skin" that completely protects the wire, while gaining more loops per box. By removing the spool core, 3 to 5 times as many loops can be packaged into a box. Thus, resulting to fewer changeovers and downtime in your binding process, and allowing you to bind more books per day. Moreover, the disposal costs associated with traditional spools is completely removed.
