Butter Boy™ makes buttering corn-on-the-cob easy and fun. Just insert half a stick of butter, pop the top and start buttering by gliding across warm corn. Also great for buttering pots, pans and anything hot while keeping your hands clean. Use at home or at picnics and barbecues. When you need more butter simply press the plunger. Store upright in the fridge when not in use. Dishwasher safe.
