The Spot-Not glassware dryer has a unique, multi-petal core and a highly absorbent micro-fiber sleeve that can be washed between uses. The flexible core conforms to the shape of almost any glass. The micro-fiber sleeve dries AND polishes. Spot-Not saves a LOT of time drying glasses, especially champagne flutes! Spot-Not reduces breakage by allowing enough pressure to dry the glass without exerting to much pressure and breaking the glass.
