The TENGA Air Cushion has 24 lubed-up air chambers which give the ultimate clinging sensation to deliver sensations never experienced before. One of the greatest orgasms guaranteed!
These revolutionary Oncaups, named after 'onanism', which is another name for masturbation, are Japan's number 1 male sex toy.
The brilliant stimulation is made possible by the unique air-cushion mechanism which allows the free exchange of air between the cushions for the smoothest motion.
A combination of nubs transform changes in air pressure into fantastic sensations from both sides of the penis. A round head at the end of the passage stimulates the sensitive tip for a wonderful experience.
The internal canal has a diameter of 0.5 inches and a length of 5 inches.
One of the most remarkable features of the Onacup is the lotion reservoir which helps keep the point of insertion point wet. There is also an air hole which lets you control pressure levels to achieve your preferred level of suction.
Before using your Onacup for the first time, remove the insert inside the sleeve.
All TENGAs come with lubricant inside. The lubrication consists of: purified water, glycerin, sodium polyacrylate, phenoxy ethanol, and paraben. Allergy tested in Japan.
