Heat Reactive: Normally black, the cuffs reveal a pink hue inside when exposed to warmth. A touch of your hand or firm pressure brings this transformation to life, adding a thoughtful interactive element.
Duality of Angel & Devil Wings:Above the key, angel wings evoke purity and protection, while the lock is paired with devil wings, symbolizing temptation and power.
To activate the color-shifting effect, avoid getting the leather wet — the finish is moisture-sensitive.
Use dry heat (hair dryer, warm lamp, or heat pack around 40–50°C) for a few seconds to reveal the color change.
If wet, blot gently and let it air dry in a cool, shaded place.
