We love our new evil eye station bracelet!  The evil eye bead is glass and sits between 2 x 4mm sterling silver beads on a plain 3mm sterling silver beaded stretchy bracelet.  The evil eye has long been symbollically linked to helping ward off bad vibes. Sold individually.
 
Each evil eye bead varies slightly due to being hand-made.

Standard size is 6 3/4" and are designed to fit slightly snug on the wrist and not extend to the hand. Measure the exact circumference of your wrist with a piece of string and add 3/4" to determine sizing.
