The Tenga Air-Tech reusable vacuum cup offers an innovative upgrade on the classic. This cup now features a removable sleeve that can be washed, making it ready for repeat use. The new airflow structure is formed from spiral ribs, allowing air to escape as it boosts sensation. Air cushion chambers to the inside amplify stimulation while textured detail pleasures the shaft for a male masturbator that delivers an unforgettable climax. The Air-Tech reusable cup comes in two varieties. Regular features the same material intensity as the Original Vacuum Cup while Strong offers a tighter, more vigorous feeling. The material is firmer and the ribs and ridges are more intense for extra sensation.
