If you already have glow in the dark stars on your ceiling, then a glow in dark butterfly and glow in the dark firefly will do nothing but complement your decor, especially since their wings move like real butterflies! Getting a set of both the glow firefly and glow butterfly will give you a little more variety than just getting either one. This is a great gift for anyone who likes butterflies and fireflies or for anyone who just goes crazy over glow in the dark items in general. To top things off the tropical glow in the dark butterfly has very beautiful colorful markings in the light whereas the glow in the dark firefly appears pure white. Place them on the plants around your house for a more realistic and natural effect. Best of all you buy both the firefly and butterfly on sale together.
