This is a 2.5" square Uranium Element Sticker that glows in the dark. They're made of durable and waterproof vinyl. These are a green under natural light and glow a bright Uranium green in the dark after being exposed to light. The glow lasts quite a while! Perfect for a Uranium Glass collector.
If you’ve purchased our glow stickers before, this is a version that is more green in natural light! it still glows well when charged under black light. 💚
