The Vagina Cylinder is made of industrial grade clear cast acrylic. The airlock release valve at the end of each cylinder will connect directly to the pump. The device is designed to create extra sensitivity in the labia. The 2" deep cup is 3" wide and 4" long.
The cylinder fits completely over the vagina, and when a Brass Hand Pump is attached and used it creates a vacuum, causing the labia to swell and tingle. For added pleasure, alone or with a partner. One size fits all.
