Banner Wind Slit Cutters is accessory used for cutting half circles (even full circle) on your vinyl banner for the purpose to decrease the resistance of the wind and that way to prolong the life of your banner. Consists of two pieces that are easy to assemble and can cut circles in diameter from 3" to full 12".
Lay your banner upside down on the surface that you don't mind scratching. Form the half/full circles on graphic side by pushing down on the knob and firmly rotating the blade handle up away from yourself. Bare on mind that practice makes it perfect!
