The LightSpeed curling brushes feature a 1" diameter at the top end providing the most comfort for the upper hand while sweeping or skipping. A 1 1/8" diameter at the head end provides more comfort for the lower hand while brushing. The patented tapered design reduces hand slippage, requiring less effort to create down-pressure, reducing fatigue. Fibreglass curling brushes feature the RS 9" complete head with approved firm foam 2.0. The RS reduces the waste from used brush parts – when time for replacement, the sleeve is the only component to replace. Reuse the foam and baseplates to limit the amount going into landfill.
