The Toko Plasto Cork is a synthetic cork for applying grip wax to the kick area of your skis. Simply rub your kick wax onto the base of your Nordic skis beneath your binding, and then use the Toko Plasto Cork to friction wax the grip wax into your base. The synthetic Plasto Cork produces four times as much heat from friction as natural cork.
I use it as a final polish of the racing ski. Not sure it makes that much of a diffrence to the oerformance of the ski. It does give it that brand new shine after I use it
