The Sealed Crystal Flesh Tunnel from the Steel Roseline® is beset with premium processed colored rhinestones. They are close packed, so that your appearance is twice as glamorous. The stones of the Sealed Crystal Flesh Tunnel are sealed by a epoxy layer. The surface of the tunnel does not only feel slick, but protects the stones from damage.
As beginner or absolute professional in the matter of soft stretching, this Tunnel is definitely the right choice.
