The flesh tunnel of the Titan Highline® is 7 mm deep and studded with premium processed Swarovski Crystals. It is externally threaded, the ring is screwed on to the outside thread of the tunnel and ensures a perfect hold.

All tunnels of the Titan Highline® are sterilisable in spite of their additional PVD coating, and due to their skin friendly material harmless to allergic persons. As a beginner or an experienced person in the matter of gentle stretching, this tunnel is absolutely the right choice.
 
A short care instruction: the crystals are not set but glued. They could get lost, depending on wear and tear.
