The 4mm is really the starting point — the sensation is subtle, almost an internal tickle. Ideal for testing if the sounding speaks to you before investing in larger sizes. Always use a sterile gel, never standard lube.
A polished steel sound 4 mm in diameter - the format for initiation to sounding. The smooth surface and anatomical curvature guide insertion naturally.
Introduction to sounding
The 4 mm diameter is suitable for beginners who are discovering urethral sensations. The sound moves under its own weight — you never push. The polished steel is perfectly smooth, without joints or roughness. The natural curvature follows the male anatomy.
Surgical steel, reliable hygiene
Stainless steel can be sterilised with boiling water or alcohol — it is the reference material in sounding, the same as that of medical instruments. The surface is mirror-polished, zero friction. The weight of the sound (25 g) is sufficient to guide insertion by gravity.
