Chrome plated dilatators or urethal sounds with a very well finished round tip in the front for a very intense c&b-play. If it is very sensitive and hurts just a tiny teeny bit – that’s nice If it really hurts discontinue use immediately. Play hygienic please even though these sounds don’t go into the bladder. Use sterile lubricant such as KY or Installagel. Size (thickness in mm): from a very thin 4 mm up to an incredible 18 mm (the large sizes are suitable for anal play only).
