Eachine1 4pcs Screw-Type Magnetic Hand Cupping Suction Vacuum Cupping

Description: Twist-top cupping is a modern development based on traditional cupping. It produces the effects of traditional cupping methods and eliminates some of the disadvantages. Each of these cups generates its own vacuum through the action of a screw valve with rubber seal in the cup body. Every piece in the Suction Cupping set is virtually unbreakable, convenient, safe and suitable for both clinical and family use. The cups' transparency lets you clearly see the reddening that takes place in the skin as cupping time increases, so you can completely control the cupping as to its effects and the optimal cupping time needed. Safe and secure, greatly facilitate the people to use, both for the hospital, but also for families. There is no need to light a fire,very easy to use, you just need to wring the Suction Cupping. If you don't know more about the knowledge of cupping,I suggest you can search on line,for there are some taboos.
