I hear Space Child by UFO when I look at this piece. Bridging the gap between Art Deco, far out thoughts, and tough babes with this design. Cuff is *slightly adjustable* to adjust tighter or wide bend gently and slowly with a fluid movement. Do not bend abruptly or rigidly. Once adjusted try to keep in this position. Bending a piece over and over again will crate weak points in the metal and over time could lead to breakage. Opening measurements will be updated shortly. Will fit "small & medium" sizes the same as my Scorpio cuffs. Please refer to that listing for size info in the meantime.
