Each Hand-L is made of high-fire stoneware clay. It's extremely durable, hygienic and temperature sensitive.

The Hand-L may be heated using hot (not boiling) water, a heating pad, sunshine, or by holding in your hands for a few minutes. It may also be chilled to provide cryotherapy applications.

To clean, simply wipe with alcohol, or wash with soap and water. The Hand-L may be used with any massage lubricant: oil, lotion, salve, ultrasound gel, etc.
