2-in-1 Electric Cupping Set: This electric cupping machine is the perfect combination of traditional cupping and modern technology. Gua Sha is based on the principles of traditional Chinese medicine. Low pressure removes harmful substances from the body, thus hydrating the body. Scraping and cupping are combined in one machine. Improved Effect and Safety: The open flame-free design is safe and secure to use; the one-touch pressure relief function instantly releases negative pressure and easily removes the cupping cup; the extended connection tube design allows for self-administered cupping for the back, shoulders, waist, and other hard-to-use areas.
