The AFH mini cupping kit uses small size cups that are ideal for sensitive skin. The surfaces of the cupping cups are sanded smooth by the sensitive cupping set, enabling a gentler cupping technique. They promote pain relief by decreasing inflammation and increasing the flow of blood in the body. There are 4 different sized cupping cups that come in the following sizes: 2.5 cm, 2 cm, 1.8 cm, 1.5 cm.
