A type of Small Chastity Cage designed to invert or push the penis inward toward the body, creating a flat and discreet profile. This prevents erections and often hides the penis entirely. Commonly used in BDSM for denial play, sissification, or feminization scenarios.
They typically feature a tube-like protrusion meant for the urethra to aid in aligning and for Peeing, it could even come with a catheter, but some are similar to Flat Chastity Cage with the cage flush to the surface with no protrusion.
Do not use this tag if the inverted design can't be seen when a flat cage is worn, tag with Implied Urethral Insertion instead. If the plug isn't worn, tag with Imminent Urethral Insertion or Unworn Urethral Plug instead. For cages that have a plug built into them but don't push the penis inward, see Dilator Chastity Cage.
