This color is quite opaque. You're unlikely to get any actual prism effect out of it. Unless you are Goth. A Goth kid. It will look perfect in your room. 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.
