For a more realistic and pleasurable experience, Tenga offers an easy-to-use and re-usable warming solution to heat up the sleeve to body temperature.
The small tube warms up almost instantly by bending the metal disk inside until it clicks. Once the gel inside has gone solid and warm it can be place inside the sleeve. After use it can be boiled to be returned to its original forma and ready for the next time.
