Tiny kaleidoscopes that use one of Chuck's handmade marbles for color. MarbleScopes are 3 inches long and hold 5/8 inch marbles. Very fun! A lens and three mirrors give this little bit o' fun a BIG image. You can change the marble in a snap for a different picture. Great for giving those marble collections a whole new look! Keep one on the coffee table with a bowl of marbles and entertain guests, young and old, for hours. $30 each plus shipping includes one marble of your choice (or let us choose). If you tell us what colors you like we will try to find a match in our shop display, or Chuck can make one just for you. The colors may not be exactly what you call for but I will do what I can to get them right for you. Note that marbles made for these MarbleScopes normally include air bubbles as they look great in the 'scopes.
