These light plastic clamps can be very securely attached to the nipples. They can be adjusted very precisely and weigh very little, so the amount of pressure they exert can be exactly tuned to the wearer's needs. However, the stationary bar features small spikes, which will ensure a tight hold, but also some piercing sensations. Each clamp includes a ring to attach weights or chains to.

Specifications: Fully extended, the two bars are spread .75 inches apart. The clamp measures 1.5 inches in width.
