Mystim Thin Finn Urethral Sound

<p>This long and smooth urethral sound is perfectly suited for the special stimulation of the penis. With some practice its 8 mm can be inserted easily into the urethra, and then create a stimulation like you have never felt before. <em>Thin Finn</em> is made of medical aluminum and polished neatly by hand. For extra kicks, it can be warmed on the heater or cooled in the refrigerator: it is designed to retain the temperature for an extended period of time.</p>
