A classic design, but with a unique twist. The E-Stim Systems Diamond Penis Plug combines urethral stimulation with the option for electro play and stands out thanks to its distinctive diamond-shaped head. The plug is crafted from solid aircraft-grade aluminum and features a mirror-smooth finish, beautifully blending metal, precision, and a unique design.
This Diamond Penis Plug is available in Medium and Large. Both sizes are 55 mm long but differ in diameter. You can choose between the slimmer Medium at 6.65 mm and the sturdier Large at 7.65 mm.
Diamond-shaped head for a unique sensation
The most striking feature is undoubtedly the diamond-shaped head. It gradually widens toward its broadest point and then tapers back down. When inserted carefully, this causes the urethra to gradually open around the head. Once in place, the narrower shaft helps keep the plug securely in position.
For the Medium size, the diamond-shaped head measures a maximum of 8.5 mm in diameter; for the Large, it is 9.5 mm. A one-millimeter difference may seem modest on paper, but with urethral toys, such a difference can be clearly noticeable.
Mirror-Smooth Aircraft-Grade Aluminum
E-Stim Systems manufactures the Diamond Penis Plug from aircraft-grade aluminum. The surface has a very smooth, high-gloss mirror finish, and the tip is carefully rounded. This is not only visually appealing but also particularly important for a product where a precise and smooth finish is essential.
Metal also has its own unique character. It feels cool at first and then gradually warms to your body temperature. For those who enjoy temperature play, the plug can be gently warmed or cooled with water before use. Avoid extreme temperatures.
Medium: 6.65 mm shaft and 8.5 mm diamond-shaped head
The Medium has a shaft diameter of 6.65 mm. The diamond-shaped head widens to a maximum of 8.5 mm. The total length is 55 mm, of which 44 mm is insertable. The wide base has a diameter of 24.5 mm, and the total weight is approximately 18 grams.
This version thus offers a clear transition between the relatively slender shank and the wider diamond-shaped head.
Large: 7.65 mm shank and 9.5 mm diamond-shaped head
Those looking for a thicker version can opt for the Large. This model has a shaft diameter of 7.65 mm and a diamond head with a maximum diameter of 9.5 mm. This variant is also 55 mm long, with an insertable length of 44 mm and a base diameter of 24.5 mm. It weighs approximately 19 grams.
The Large offers an extra millimeter in diameter at both the shaft and the widest part of the head, making it the more intense of these two variants.
Ribbed base for extra grip
E-Stim Systems has added multiple grooves to the base. These provide your fingers with extra grip when your hands and the toy have become slippery from lubricant. At the same time, the ridges can add extra texture when the base rests against the glans.
The wide base also clearly indicates where the insertable portion ends. A small detail, but exactly the kind of practical finishing touch that matters with this type of precision toy.
4 mm connector for electro play
The base features a standard 4 mm connector, allowing the Diamond Penis Plug to be used as an electrode within a compatible electro play system. The plug functions as a monopolar electrode and therefore always requires a second contact point to complete the circuit.
That second contact point could be, for example, a suitable conductive rubber sleeve or a compatible electrode from E-Stim Systems. Connect the plug only to equipment specifically designed for safe electro play and follow the manufacturer’s instructions.
Use and Maintenance
Urethral play requires care and hygiene. Therefore, clean the Diamond Penis Plug thoroughly before and after each use, and use a generous amount of a suitable lubricant. Never force the plug; choose only a diameter with which you have experience and that can be inserted comfortably without resistance.
Because the plug is made of solid aluminum, cleaning is easy. E-Stim Systems recommends warm water with a mild detergent or a suitable sterilizing solution. According to the manufacturer, the solid aluminum can also be boiled. Allow the plug to dry completely after cleaning before storing it.
