Material and making: The air extraction jar is made of organic glass or transparent engineering resin material. The piston on the jar top is used to control the air extraction, and the principle of mechanical air extraction is used to form negative pressure in the jar body, so that the jar body is adsorbed on the selected part.

Advantages: No fire or electricity is required for the use of the air extraction jar, which eliminates potential safety hazards and does not scald skin. It is easy to operate, can be widely used for personal and family self-care and is a more popular new cupping device.
