Mystim Proper Finn

With a diameter of 10 mm, Proper Finn is two millimeters thicker than his cousin Thin Finn and so stimulates the penis even more intensely. His elegant design with a softly rounded tip and smooth transition between the poles render the insertion into the urethra a matter of little practice.

Proper Finn 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.
