Mystim Thin Finn Urethral Sound – Silver Medical-Grade Aluminum

Mystim Thin Finn is a urethral sound made of medical-grade aluminum, designed for urethral stimulation. The sound has an 8 mm diameter and features a smooth, hand-polished surface for a refined finish. Medical-grade aluminum construction allows the sound to retain temperature when warmed on a heater or cooled in a refrigerator, enabling temperature-based sensory variation during use. With practice, the Thin Finn can be inserted into the urethra for specialized internal stimulation. The polished surface and temperature-retention properties support controlled sensory exploration. Material: Medical-grade aluminum. Color: Silver. Country of origin: Germany.
