2 Small and 2 Medium Twist Action Suction Cups

Two small size with an internal diameter of 1.9cm and two medium size with an internal diameter of 2.8cm. 

Place the suction cup on the skin and twist to retract the plunger, creating a vacuum to suck whichever sensitive body part you choose.

Works best if you create a strong seal between the cup and skin. Wetting the skin a little can improve the seal, oil based lubricants create a better seal, but for the best seal we would recommend using a petroleum jelly product such as Vaseline.

We get these from a manufacturer well known for their high quality products. These cups are made from a denser material and have a much longer lifespan than their cheap counterparts. Over time the seal inside the cup can begin to dry out and the cup lose it's suction. Adding some petroleum jelly to the inside of the cup can refresh the seal and bring the cups back to new. I know people who have been using these exact same cups for almost 20 years already and they're still going strong.
