Replacing the popular EZ Plastic cup sets, this new cupping set design from Korea contains plastic cups that are shock and heat resistant, which allows them to be sterilized in boiling water. Each cup also uses easy release air-locking valves. Cup sets include a pistol grip hand pump and carrying case. The 17 cup set also includes a 21" extension tube. 17 Piece Set includes: 2" dia (13), 1.8" (2), 1.6" (1) and 1.3" (1)

Each suction cup may need the seal on the nipple to be loosened before use for proper suction. If cup does not work (no suction), lift and twist airlock nipple (part that attaches to pump) several times. This should loosen the seal and enable the cup to create proper suction.
