Our set of 4 different sizes of glass sounds is designed for experienced users in the area cock stuffing. They provide extreme stimulation and sustainable dilation of the male urethra.

The nominal diameter is approx. 6 mm (0.24"), 8 mm (0.30") and 10 mm (0.40"). The total length is approx. 20 cm = 8 inches. Our sounds are equipped with a round head, which prevents them from being inserted too far.

The glass used is highly break-resistant and has an extremely smooth surface. However, the outer surface is twisted to create an almost plaited structure. This allows the sound not only to be inserted but also "screwed in", resulting in even more intense sensations for the user.

The borosilicate glass we use has a mirror-smooth surface for easy insertion. With a few drops of VERYDEEP, MEO's medical grade lubricant, even our most sizeable urethral sounds will slide right into you.

Material: odorless, hypoallergenic and ultra hygienic: easy to clean, even in the dishwasher, or with our VERYCLEAN cleanser. Borosilicate glass denotes a highly chemical-and temperature-resistant glass that is used primarily for glassware in the laboratory or glass vessels in the household..It has excellent tensile strength, is nonporous and 100% free of phthalates.
