Designed using quality materials, this masturbator is made of soft, flexible material. Its special feature is the so-called Air-Tech mechanism, which allows the chambers in the insert to fill with air during movement and then empty, creating a special suction effect. Cleaning : before and after each use, the insert should be washed with lukewarm soapy water and a utensil cleaner, after removing it from the case. A water-based lubricant is recommended, a sample of which is included in the package. Translated with www.DeepL.com/Translator (free version)
