Thanks everyone! I bought the princess tattoos in the party supply section of Target and the Frozen ones from eBay. Firefly is a brand of glow in the dark nail polish. I used super glue to attach the crystals and sealed with clear nail polish and firefly
I ordered the firefly directly from their website. I applied the tattoo to the clean band, attached the crystals and put a Sally Hansen clear top coat over it. I then used a glitter polish or the firefly polish. They glow really well!
