Amazing sensations with this versatile accessory!
These are different than you will find elsewhere. They don't just have a sheet of flexible rubber tucked around them, they have a solid electroconductive rubber ring that snaps on to the edge for a perfect fit that doesn't come loose at inopportune moments. Use a little gel for a great suction seal. Release the pressure easily by pushing the button on the top, partially or completely. Customize the pressure by the number of squeezes on the suction gun handle. A great way to combine multiple sensations into one product!
The cup comes as 3 pieces to put together, and work best if assembled as such. Can be used with or without the electrical ring. The overall length is 8", base and middle sections are 76mm/3" long with top cup measuring 2". The inner diameter of the cups is 2". The rubber ring has inner diameter of 38mm/1.5", outer diameter of 56mm/2" wide. Depth of rubber ring is 7mm/0.3" with a pin hole for 2mm pin connector. The tubing is 25 1/2" long including plastic connectors.
Very easy to use, no adapter required. Just plug in a standard 2mm pin lead to hole in the rubber ring.
Buy the penis cup and ring only, or a full set including the pump and extention tubing.
