These look much more wicked and evil then they are, yet tighten them down enough and they still provide a nasty bite.
The flat bar at the bottom provides more than a squeeze rather than a pinch. The little spikes along the top bar work well to provide added grip so that the nipple does not escape.
Tighten these spiked nipple clamps down using the tall, silver adjustment screw to achieve the desired tightness and pressure. You decide how much pain or pleasure is inflicted on the wearer of these devilish little clamps.
The attached chain is ideal for adding your favorite weights. Each movement will be amplified, intensifying the sensation from the weighted chain swinging between the wearers breasts.
The clamp opening is roughly 0.75 inches wide and 0.5 inches tall, and can be closed completely.
