This listing is for one hundred 5mm light mint colored Czech Uranium glass round beads. These beads glow under blacklight due to the Uranium used in making and coloring the glass. These beads glow brightly under blacklight. 100 beads is about 18.5 inches, enough for a necklace or a couple of bracelets. These beads are new and have never been used, but are old stock. Thanks for shopping my closet, I ship quickly and pack my orders with care.
