Cupping has been used in traditional medical practices in China for hundreds of years.
This suction cup is made of durable Corning glass (which molds comfortably to the skin) while the bulb is made out of long lasting rubber.
The glass cup is 1 and 3/8" in diameter. The rubber bulb creates a quick suction and prevents any fumbling with fire and tweezers. All the components of the suction cup can be easily cleaned. The Rubber bulbs are also replaceable.
