This color is almost opaque, so you're not going to get much in the way of rainbows out of it. Unless you are Goth. A Goth kid. It will look perfect in your room. Particularly at night. It's cheerful like lots of other cheerful Goth things like North Korea, Slipknot and falling asleep in a cave. These are not leaded glass so the rainbow effect will be less or not at all but you still get the looking through a fly's eyeball effect if you get too close. They can't take that away from you. These have a hole across the top so you can hang them from fish line. Some may have slight scratches or nicks on them. Sorry.
