Hot stones
$15Two kinds live in the suite. Say which one you want, or leave the choice to the area being worked.

Basalt
Smooth volcanic stones, warmed and placed along the body or used in the hands. They hold heat, so the muscle can soften without having to push harder.

Himalayan salt
Pink salt stones, smoothed and warmed more gently than basalt. The feel is mineral and a little brighter. People choose these when they want stone work without as much heat.
