Excrucio is an imaginative urethral plug made of durable, easy to sterilize stainless steel. Pleasure is increased by the intense pressure once the extra wide urethral insert is in place. Four interchangeable rings provide a customized fit, one behind the cock head and one along the shaft. Long and smooth, the cum-thru tube allows for ultimate satisfaction. Stainless steel is non-porous, hygienic, easy to sterilize, temperature and impact resistant, and offers a long-term value. The lower ring is fixed at the end of the supporting arm, which is designed to sit mid-shaft. The upper ring, closer to the head, can slide up and down along the supporting arm, to allow for changes in size and normal movement, as well as a customized fit. The hollow urethral insert is rounded at the end and polished smooth, with no seams, burrs, or ridges, and can be unscrewed for easy cleaning. The supporting arm is stable and welded strongly, for a durable toy that will last you many years with proper care.
