The Pubic Enemy No 1 is our neat and transparent cock cage with e-stim function: He lets you keep a boisterous willy pent up under lock and key so that he can't get stiff until the mistress, or the master, comes with the key and lets him out. With the conducting surfaces, left and right, the prisoner can be treated to your heart's content with tingles, twitches or pulsations in precisely the intensity he deserves. Because his conductive surfaces can be taken out in no time at all, our chastity belt for wayward gentlemen is perfect even for those who haven't yet discovered e-stim. And if a prisoner gets too cocky later, the conductivity can easily be restored. Dimensions: The Cage inner diameter: approximately 1.34 inches (34 mm e) at the mouth, 1.85 inches (47 mm e)at the widest point, length: 3.23 inches (82 mm e); can be increased with the 3 spacers included in the delivery. Each spacer adds approximately .16 inch. The Clasp inner diameter is variable in 6 steps from approximately 1.3 inches to 2.05 inches. <br /><br />Please note: this is an attachment for the Tension Lover Kit or Pure Vibes Kit.
