The UltraSound Smooth 12mm features an impressive design and is suitable for experienced players in BDSM. Made from pure stainless steel with a mirror finish, it is extremely smooth and shiny, featuring a slim, tapered tip and rounded end.

The design allows for gentle insertion, facilitating the dilation of the urethra and making it easier to use the full thickness of the product. With a difference of 2mm between the tip and the shaft, it offers gradual dilation (from 10mm to 12mm) during gentle insertion, helping to open the area for the full diameter to be accommodated.

All E-Stim Systems UltraSounds boast a sleek character with a ribbed base for better grip, even with slippery fingers, and are equipped with a 4mm plug, according to industrial standards.
