Create magical glowing unicorn nails! The dual-tip nail pens allow you to not only paint your nails, but to easily and precisely detail them with the fine pen tip. Apply a base coat with the broad brush in one of the 4 fun shades, then apply a foil sticker and simply color in with the detail tip. To activate the 2 glowing nail polish colors, simply expose nails to the light for a few minutes and then watch them glow in the dark! The perfect activity to do with friends.
