The flat ovular basalt stones are the most popular choice of stones used by therapists as not only do they retain heat due to their high polished finish, but they are also the most comfortable and convenient shaped stones to use.  The round, elongated shape fits perfectly in the palm of a therapist's hand, ensuring the stone is used efficiently.  The rounded, narrower edges can also be used to pressurize and knead particularly tense muscles and areas during treatments.  This feature is unique to the flat ovular basalt stone.Hard to find model!!!
