Totally Bamboo's Barkeeper's Salt Box is distinctively attractive, super strong, and totally "green". It's perfect for holding and placing the rim of a margarita glass in before filling the glass w/a margarita. A small magnet on the base and lid ensures a tight seal. Originally meant to house cooking salts this box has found its way into many places! A laser engraving on the top of the box ensures your logo will be seen for years to come.
