Description
The Slim Finn™ is a bi-polar aluminium urethral sound — hand-polished, lightweight at just 15g, and built for electrical stimulation of the urethra. A compatible Mystim power box is required and sold separately.
Urethral sounding involves inserting a smooth probe into the urethra — the opening at the tip of the penis — for deep internal stimulation that cannot be replicated externally. The Slim Finn™ is 6mm in diameter — a slim, manageable size that makes insertion more approachable with practice and adequate lubrication.
Both ends are gently rounded, and the transition between the 2 bi-polar contact zones is seamlessly smooth — no ridges or abrupt changes in shape. The poles isolate within a few centimetres of insertion, so stimulation begins almost immediately as the sound is introduced.
The hand-polished aluminium responds to temperature — warm briefly in warm water or cool in cold water before use for an added dimension alongside the electrical stimulation.
Connects via Mystim round plug — compatible with Mystim Cluster Buster, Tension Lover, and Pure Vibes. A Mystim round plug to 2mm adapter is available separately for use with other power boxes.
Takes 2x 2mm pin connectors — lead wires not included and sold separately.
This suits users exploring urethral e-stim who want a slim, lightweight aluminium sound with temperature play and Mystim power box connection.
