You'll love how simple these are to use. The tweezer-style clamps apply pressure from two sides - just slide the ring sizer up or down to increase or decrease the pinch level. Loose or tight, the soft silicone tipping each end cushions and protects your or their skin.
In nickel-free metal (iron) and silicone, the DC3's can be spot-cleaned as needed. Each clamp measures approximately 2.75"/7cm, and the chain is about 12.5"/31.8cm end to end.
