like these are strangely good, i dont know how it works, but i have fibromylagia and often in loads of pain, i used them on myself last night and the pain slightyl moved whilst they were on, early days but im defo going to continue to use these, what ive also found out is dont use them neck above, leave you with love bite looking marks from the pressure, ahah keep below the neck. comes well packaged with box and black bag inside, and purple cupping thingys. great product and good quality kit
