UPKO - Finger Bound Play Metal Thumb Cuffs – Claim Elegant Control

Discover compact restraint with a thrillingly powerful edge. UPKO - Finger Bound Play Metal Thumb Cuffs transform the classic thumb cuff into a refined BDSM accessory made for control, tension, and erotic surrender.

Inspired by traditional thumb cuffs, UPKO replaces the usual double-lock design with a progressive screw-style mechanism. Turn the rotary knobs at both ends to adjust the intensity of restraint, from teasing control to firm, helpless stillness.

More portable than traditional handcuffs yet just as effective, these zinc alloy thumb cuffs invite intimate bondage play with style, precision, and sophistication. Use them behind a chair, with nipple clamps, a gag, or attach a leash chain to a choker for daring power exchange and deep erotic connection.

How To Use

• Place the thumb cuff with the holed side facing downward.
• Insert thumbs while the rotary knobs are at their outermost position.
• Turn the knobs at both ends to adjust the restraint level.
• Emergency tip: the restrained partner can interlock their fingers and operate the knobs to loosen the cuffs.
