Complete kit eliminates guesswork in size progression
The Nanma Knot-Knot Silicone Urethral 3 Piece Plug Set from NANMA Corporation is a graduated urethral sounding kit that delivers controlled stimulation through three progressively sized plugs. Each piece features a tapered shaft with rounded ball tip for smooth entry and secure handling. The soft yet firm silicone construction provides comfortable insertion while maintaining the firmness needed for guided urethral exploration.
Each plug features a carefully tapered shaft that guides entry smoothly into the urethral opening. The rounded ball tip reduces friction during insertion while the graduated sizing lets you progress at your own pace. Start with the smallest piece to get comfortable with the sensation, then advance to larger sizes as your body adapts. Our silicone medical sounds collection offers similar progressive training options for men building their urethral play experience.
The matte silicone surface provides better grip during handling while the non-porous material stays hygienic between sessions. The bulb end acts as a natural stopper, preventing over-insertion and giving you confident control throughout your session.

This kit takes the guesswork out of urethral exploration. You get three perfectly sized pieces that work together as a training system, not just random sizes thrown together. The soft silicone feels reassuring for beginners while the bulb ends keep everything safe and controlled. It is urethral play designed for real progression, not just experimentation.
Real experience:
I started with the smallest piece and was surprised how smooth the entry felt. The tapered design guided everything naturally and the bulb end gave me confidence I could not go too far. After a few sessions I moved to the medium size, and the progression felt perfectly paced. The matte surface never slipped in my grip.
The sensation builds gradually as you move through the sizes, creating this incredible fullness that intensifies with each piece. There is something deeply satisfying about the controlled insertion, knowing you are in complete command of the depth and pressure. The silicone feels gentle but substantial, giving you that secure feeling throughout the entire session.
