I've always found kaleidoscopes pretty magical, and even better one's you don't have to look through a scope to see. Turning the handle here rotates one of two colorful round glass slides, making kaleidoscopic patterns as it shifts in relation to the static one. Just a lovely thing, especially great set near a window to hold to the light for optimal viewing.
Overall: 7 3/4" long including handle. Kaleidoscope glass is 1 3/4" in diameter. Very good antique condition and handle turns very smoothly.
