This listing is for one 1" prism. Originally developed for aeronautics, this holographic glass is used in the windows of spaceships. It is equally beautiful for use as suncatchers in your home. This high quality "space glass", also called dichroic glass, breaks the light into the most beautiful rainbow speck display that you can imagine. I took this picture to try to capture it, but it is even more beautiful in person. Get lost looking through the glass like a kaleidoscope and see the world in multi color. It will also keep kids occupied for a while. It is truly mesmerizing.
Keep it on a shelf in your home, or somewhere where direct sunlight can hit it, to get the full effect.
Makes a great gift or stocking stuffer.
