When I was playing “find the UV reactive beads I don’t know I had” by turning off the lights and shining UV flashlights at boxes of beads, these lit up SO BRIGHT. Like startlingly bright - the photo under UV doesn’t really convey how bright they are. Vintage plastic of some sort salvaged off a costume jewelry necklace and accented with some of the last of my Swarovski crystal stash.
Sterling silver earwires unless you opt to
This is part of the fauxfire collection - 80 uv-reactive or glow-in-the-dark shinies! All of the UV-reactive pieces will react under 365nm UV light; some will react differently or not at all under 395nm UV light.
