A smooth stainless steel exterior, with rubber-coated balls inside so the movement stays very quiet. Worn internally, they answer to movement rather than to a motor. Two spheres, with a satin cover, a user manual and a warranty card in the box.
Specifications
- Material: Smooth stainless steel
Steel does not react with any lubricant, so the choice is down to preference rather than chemistry.
Wash the steel with a mild unscented soap and let it dry completely before storage. The material takes hot water without trouble.
