Longstones are particularly long and thick freeform massage stones, which are especially suitable for deep massages and application on large muscle areas (e.g. on the back or legs).
The Longstones are approx. 13cm long and 2.5cm thick.
Anthophyllite is used in stone healing according to Mchael Gienger to strengthen the self-worth and recognition of one's own person, as well as for support when it is necessary to give one's own interests a space and to maintain it in the long term.
