This ElectraStim Electro Ball Stretcher 20mm is a purpose-built unipolar accessory for focused scrotal stretching. It’s made to sit around the scrotum and is sized for a measured, reliable fit: outer diameter 2.28 inches / 5.8 cm, inner diameter 1.45 inches / 3.7 cm, 20mm height and a mass of 238g (8.39oz). These confirmed dimensions make it straightforward to check fit before use.
As a unipolar electro accessory it is intended to be used with compatible unipolar equipment to create controlled electrical sensations while providing a consistent stretch. Its weight is part of the experience — substantial enough to provide a steady pull but simple to assess against your own comfort and preference.
Care and measurement are essential: ensure the inner diameter suits your anatomy and familiarise yourself with unipolar electro systems and safety practices before use. If you’re uncertain about compatibility or fit, consult product instructions or ask a specialist retailer. The ElectraStim name denotes a product designed to integrate into electro play setups where measured sizing and predictable behaviour matter.
