The Tenga Flex is distinguished by its gentle spiral-shaped grooves and outstanding suction action.
The flexible pleasure tunnel includes a variety of textures and tightness levels. The spiral-shaped grooves on the flexible outer sleeve rotate back and forth as the sleeve is moved up and down. The amount of stimulation a person receives is determined by how hard they squeeze.
At the top of the toy, there is a hole. The suction effect can be controlled using a finger.
After each use, the pleasure tunnel should be taken from the outer case and washed under running water. Then let it air dry on the built-in stick.
A sample of lubricant is included, as well as an instruction manual.
