Starfire Combo Interchangeable is a dazzling lacquered brass kaleidoscope with a 3-mirror system. It uses two indendently turning wheels at a time, but there are five wheels in all, because they're interchangeable. The majority of the image you see as you look through the kaleidoscope is created by the primary wheel, or the one closest to your eye, and the secondary wheel provides background or accent image. When you unscrew the knob holding the wheels and trade them out front-to-back, you are rewarded with an entirely different kaleidocopic view. So with five wheels in total, imagine all the permutations!
The wheels are created from combinations of colorful stained and textured glass, faceted glass gems, and Brazilian agate stone slices, and the image created is made vivid by the help of a powerful magnification lens in the eyepiece. This kaleidoscope measures 9" long x 1.5" in diameter x 2.5" tall when sitting on its custom wooden stand.
