A Deep, Electrifying Dive Into Pure Pleasure

The Mystim Proper Finn delivers a whole new level of urethral play, blending smooth insertion with precise electro-sensations for those ready to explore deeper thrills. This estim sounding rod is crafted to glide in comfortably with practice and lubricant, thanks to its gently rounded tip and seamless finish. Once in place, it works as both a urethral plug and a teasing sounding toy, combining internal stretch with the pulsing, tingling current that makes urethral sounding such an addictive experience.

Made from hygienic medical aluminium and polished by hand, Proper Finn doesn’t just feel good – it looks stunning, too. It’s designed for safe and satisfying urethral dilation, with isolated poles only a few centimetres apart for targeted stimulation. Connect it to a Mystim power box like the Pure Vibes, Tension Lover 2 or Cluster Buster, and the penile sound instantly comes alive with soft tingles, deep pulses or intense rhythmic waves.

Heat it up for a slow, melting warmth or cool it down for a sharper edge – temperature play makes the entire journey even more exciting. Whether you prefer slow-building sessions or edging yourself right to the brink, the adjustable electrostimulation lets you tailor every moment to your mood.

Behind its sleek design lies genuine craftsmanship. Mystim’s team hand-polishes each piece to a flawlessly smooth finish, creating a tool that feels refined, precise and built for unforgettable pleasure. Proper Finn may disappear down the tubes – but the sensations it delivers won’t be forgotten anytime soon.

• Premium Medical-Grade Aluminium

  Made from polished medical-grade aluminium that feels smooth to the touch and glides in easily when paired with a quality water-based lubricant.

• Comfortable Rounded Tip

  The gently rounded tip and seamless body support more controlled insertion and gradual urethral dilation as your experience and confidence grow.

• Built-In Bipolar Electro Contacts

  The two integrated poles spring to life when connected to a Mystim electro sex power box, turning every subtle movement into a focused, throbbing e stim pulse for intensely targeted penis stimulation.

• Temperature Play Ready

  Can be gently warmed or cooled before use to add an extra layer of sensation, making each session feel fresh, surprising and uniquely intense.

• Durable, Hygienic and Easy to Clean

  The solid aluminium body is non-porous, easy to clean and built for long-term use.

Electrosex (also called e stim or electrostimulation) uses gentle electrical pulses to stimulate your body’s nerve endings, creating a unique tingling or throbbing sensation that feels completely different from vibration. When connected to an electro sex power box, compatible toys or pads send controlled pulses through the skin to heighten sensitivity and build deep, rhythmic pleasure. It’s a safe, customisable way to explore new levels of stimulation – whether you’re teasing yourself or sharing sexual pleasure with a partner.
