Wide crusher cuff with a 5-4-5 pattern of small 77 British cone studs around a single bondage ring.
Sizing: Buy the largest size that will "fit" your wrist for maximum stud coverage. My wrist is 7" around and the M/L fits snugly on the tightest adjustment hole. The M/L size will fit 6.5"+ wrists and the S/M size will fit smaller wrists.
