The "Butterfly" brass teleidoscope by David Kalish is 4 1/2" long and has a diameter of 1 1/2". The 3 mirror system gives the image a quilted look. A teleidoscope gives the item you are looking at a kaleidoscopic image. The photos here are of a picture of a floral bouquet and a Morton salt container. A teleidoscope gives you the opportunity to see your surroundings in a whole different perspective. Made in the USA by David Kalish.
