Gua Sha stone for Chinese deep tissue massage therapy

This is a printed Gua Sha "stone" http://en.wikipedia.org/wiki/Gua_Sha Gua Sha is a Traditional Chinese method of deep tissue massage that can really help tired muscles and tendons feel better and heal faster. It feels similar to rubbing your lower legs after a long day in tight socks or boots. It is a deep tingly and satisfying sensation and can be applied to legs, arms and backs etc... use a small amount of oil or lotion to lubricate the skin, I use it in a fitness center steam room as well.
