Some cages make you feel like you’re wearing a piece of plumbing. This one disappears.
No base ring means no scrotum math, no pinching at 2am, no moment where you’re standing in a public restroom wondering if something is about to go wrong. The part everyone dreads about chastity — the fitting, the adjusting, the quiet dread of getting it wrong — just isn’t here.
What’s here instead is a small, rounded cage that sits over your glans only. Resin, so it weighs almost nothing. Openings all around, plus a clean hole at the tip so using the bathroom stays simple. You don’t have to think about it.
The coronal sulcus ring is what makes this work. It sits right in that groove behind the head and holds everything in place — not through pressure on your body, not through bulk or weight, but through fit. Nine sizes, because the one thing worse than no control is the illusion of it. Yours will actually fit. And once it does, there’s no pulling out. Not through arousal, not through patience, not through convincing yourself you almost can.
The lock goes on and that’s the end of the negotiation.
It comes in pink, pink-blue, or black. You probably already know which one.
