These unique stones with their unique grips, benefit in two ways from the handles on top. Firstly, they give the stones more bulk, meaning more space where heat can be stored, and secondly they make it easy to slide the stones along the body. They come in 2 sizes 7cm Ø x 2cm thick at the circumference x 4.5 cm thick in the centre and 9cm Ø x 3cm thick at the circumference x 5.5 cm at the centre.
