• DESCRIPTION

There’s something quietly elegant about being locked—and the F303 captures that feeling in steel.

At just 146g, it’s lightweight enough for daily wear, but still firm enough to remind you you’re caged. The body features a flat-profile design that stays discreet under clothing—no awkward bulges, no shifting. Just a subtle presence only you (and maybe your keyholder) know about.

But the real showstopper here? That butterfly-shaped faceplate.

It’s more than a design—it’s symbolic. Graceful, restrained, and completely exposed. The butterfly’s wings form wide vented cutouts that let skin breathe, keeping everything dry and clean, even during long-term wear. No trapped heat, no sweaty discomfort. Just a cool, breathable kind of captivity.

The abdomen of the butterfly rests perfectly against the tip, leaving just enough space for natural function. You can pee freely without unlocking, thanks to the clever positioning of the central gap. It makes a huge difference for anyone doing long sessions or 24/7.

And here’s a detail I personally love: the silver-core lock. It’s subtle, but it matters. Most cages on the market still use those yellow-brassy lock cores that totally clash with polished steel. This one? The lock blends right in, clean and seamless—no visual distraction, no mismatch. Just one smooth, unified statement.

The Butterfly Flat is the kind of cage that doesn’t scream for attention—but it doesn’t need to. It’s quiet restraint, elegantly expressed. Subtle, deliberate denial. And once you feel the way it sits—snug, balanced, and effortlessly aligned—you’ll know it was designed for someone who truly understands the chastity mindset.
