This item is approximately (65) 6mm Round Medium Blue Cat's Eye Fiber Optic Beads temporarily strung on monofilament line. These are really pretty beads that I have loved since I first discovered them a couple years ago. I have heard them called the man-made version of what tiger's eye should have been. They do resemble natural tiger's eye, but were created in colors you'd find in a child's crayon box. Great for making necklaces, bracelets, earrings and more. Available in the following (Left to Right in photo): Reddish-Orange, Green, Medium Blue, White, Light Blue, Pink, Purple, Light Gray, Light Brown, Yellow, Lime Green, Light Purple, Brown Dark, Blue, Aqua, Dark Gray
