this is an absolutely ideal shape and edge, thickness and grip to alleviate usage of the upper body in relieving tension in the lower body. Self-massage is difficult to achieve without simply moving the tension elsewhere, I find. Full lower body gua sha 2x weekly and daily AM abdominal massage (sometimes a PM) has made a difference, from the day I got her in the mail. The foam is so reusable, and too cute to throw out. The only single thing I would say is that somehow I feel embarrassed by the brand name, something I’ve never dealt with and I love promoting products I love, but I feel the language… it would alienate a lot of my friends. So I’m gatekeeping for now……….
