Introducing the Mystic Bond Collection - Collar with Nipple Clamps. 
Innovative BOA® Fit System with erotic stimulation. By rotating the button, the strings connected with the labia extender clamps will be tightened, enabling stimulation and control of sensitive areas.
The easy one-handed operation allows for easy retraction and release for smooth control over the strings to immerse yourself in the fun of the play.

How To Use
1. Rotate the button clockwise to tighten the two strings.
2. Gently pull up the button to pull out and release the strings.
3. Push the button back to its original position and rotate it clockwise again to tighten the strings.

Please kindly note:
When you need to release them, please pinch the two steel strings and pull them out at the same time. To prevent tangling, retract the strings to their shortest length before storing.
