Premium Cupping Set: All elements of this set have been redesigned and upgraded: the suction gun (new model, more comfortable), the extension cord (which can now be attached directly to the suction cups without adding additional tips), the box (elegant, magnetic closure, polystyrene-free) or the quality of the suction cups Includes 12 super strong, durable suction cups: Unlike other sets, our set includes 10 large suction cups (diameter: 6.1 cm). This allows you to suction large areas of the body (such as the back). But there are also 2 small curved suction cups (diameter: 4.4 cm), which allow you to suck smaller surfaces (such as the neck) more precisely. Still our large instruction manual: a step-by-step guide for beginners and experienced users, and we have now added an e-book to take it a step further in practice.
