cupping is a method of acupressure that applies a vacuum to the
receiver's skin. By heating the air inside the cups and then placing
them against the skin, a vacuum is created as the air cools. The
suction created can be therapeutic or erotic.
The air inside the cup can be heated with a candle, lighter, match,
or even a cotton ball soaked in alcohol. The trick is to heat the air
in the cup without heating the glass too much. To ensure a tighter fit,
massage oil or lube can help prep the site that the cup will be applied
The set includes three cups: small (1 3/8" diameter opening), medium (1 3/4" diameter opening), large (2" diameter opening).
