My girlfriend has glow in the dark stars, Plastic, green or yellowish in color. The thing I don't like about them that you can't turn them off, and they do look like stars, as in 5 points, real stars don't have five points, but the glow in the dark paint may look better. It all depends on what you want.
Remember you can't turn them off, but then again, they don't glow for that long anyway with out a "recharge" of light. Maybe get a black light in your room.
