These Electrastim Scrotal Rngs measure 52mm, 60mm and 68mm (approximately 2, 2.35 and 2.7 inches) in diameter, so most penis owners will find their perfect fit in this 3-pack. I recommend using some electro-conductive gel along the inside of the cock ring for the best possible clarity of sensation. Each ring has a single 2mm pin.

Electrode Type:

Uni-polar for external stimulation - they take 1x 2mm pin connector. 3 rings per pack, only one to be worn at once. You will need a second uni-polar electrode to complete the circuit. To feel the sensations described you will need to connect a ring to an e-stim control box.

Dimensions:

Included in the set are 3 cock rings with the following measurements:

• 52mm (approximately 2 inches in diameter).
• 60mm (approximately 2.35 inches in diameter).
• 68mm (approximately 2.7 inches in diameter).

Materials: Made from a solid bar of aluminium T6082T6.
