Both Medison devices rely on elasticated thread to achieve strangulation of the foreskin. This thread is made of hypoallergenic material and specially imported, we are informed by the manufacturer, from Japan. Available sizes are 20, 22, 24, 26, 28 and 30mm diameter (adult device) and 11, 12, 13, 14, 15 and 18mm diameter (child device).

Both designs are sterilised to internationally accepted standards by the EO (Ethylene Oxide) process.
