This is the third time i have bought a package over the last 5 years, every time my neck/shoulder seize up, and i am currently being treated by Satoshi - a gentle giant - having the size and strength to dig deep into the tissues and the pressure points for immediate pain release and the gentleness to acknowledge my breathing, pain thresholds and the sensitive neck region. Having someone hold your head in one hand is risky but I am 100% confident with Satoshi.
