Transform your bondage play with the E-Stim Humbler. This kinky tool not only keeps them in a submissive position but also delivers stimulating electric shocks. Constructed from smooth wood, it is both durable and safe for intense sessions. Featuring two in-line adapters, you have twice the options for electric play, and it is compatible with most E-stim kits and boxes. The built-in locking mechanism enhances the restraint experience, and two keys are included. The hinged opening allows for easy adjustments while keeping everything aligned perfectly.Unlock the humbler to open. Hinges will open up to 90 to allow plenty of room to pull the testicles into position. Slowly close, taking care to adjust testicles if needed to prevent any unintended pinching. Lock will engage once returned to the closed position. Insert 4mm banana unipolar leads into the metal connection points on the humbler. Pin to banana adapters can be used if your leads have 2mm pin leads. Connect leads to your power box (not included). Adjust intensity and stimulation mode using your power boxs controls according to its instructions and as you desire!
