Description
Designed for Flat, Secure Wear
The UltraFlat Inversion Chastity Cage is made for those who want the flattest, most discreet look possible. It comes in two styles—Innie and Micro—both designed to stay close to the body without drawing attention. The Innie model is especially unique. The cage sits behind the ring, creating an ultra-low profile that stays steady and hidden under clothes.
A Cage That Can Change with You
The head of the cage features a dense mesh structure with a long opening in the center for easy cleaning and use. Its flat front holds your tip gently in place. For those who like to switch things up, every size is compatible with an innievader attachment, letting you change the flat design into an inward-locking setup whenever you want.
Well-Made and Built to Last
The UltraFlat is crafted from medical-grade nylon resin. Every part is carefully shaped and finished, with smooth edges and solid construction. It’s designed to be durable and skin-friendly, so you can trust it to perform over time.
You can also purchase the innievader attachment separately.
