Bipolar Ballstretcher Cockring on 2.5mm Plug

Made of highest-grade aluminum, these new insertables are solid, durable, and extremely comfortable.  Aluminum takes less power to operate and is more affordable than the comparable stainless steel models.  They are a bipolar design, with a 2.5mm plug. The rubber rings on this are stretchable for placement (but not electroconductive).

Inside diameter is 34mm. (1 inch = 25mm)
