Opaque Glow in the Dark 3-Inch Plastic Spike
Can be attached with a little bit of super glue if you scratch up the base first. Alternately you can drill small holes along the base, and sew them down.
Glow in the dark claws will glow in the dark once properly charged under a bright light. By "charged" we mean you let them sit under the bright light for an extended period of time. The best light is either direct sunlight, or a UV light. These are all cast in an opaque resin.
