Sapphire.
The Phoenix Sapphire represents state of the art technology combined with comfort and style.

The image above shows the mold proof, called an SLA. The actual cage will be totally transparent. Apart from the
nylon lock pin, the Sapphire is comprised completely of acrylic and, given a plastic padlock, is metal detector safe.

The cage has an internal diameter of 36mm and is mounted to a 50mm (internal diameter) back band.

A 60mm back band will also be available (not pictured here).

The internal pressure pad can be dropped into the cage to the added depth of the two top spacers seen here just
underneath the padlock. Pull out is extremely difficult.

During arousal, only the top of the glans contacts the inner cage wall which makes in-cage activity an unfulfilling experience.
