The Holy Trainer V4 Nano Clear puts your denial on full display. At just 58mm, this snug chastity cage keeps your cock caged, visible, and completely out of reach.

Made from medical-grade bio-resin, it’s lightweight, discreet under clothes, and strong enough for long-term chastity training. The curved design and wider base ring offer a smooth, secure fit that won’t shift, no matter how much you squirm.

Every ache, twitch, and frustrated throb is exposed behind the clear shell, making it perfect for teasing, torment, and total submission.

Crystal clear. Cruel control. No escape.
