Kaleidoscope - 8" Yin Yang in Blue & White Wavey Glass by David Sugich 

Yin Yang is a gorgeous kaleidoscope, offering a unique viewing experience. With a 4-mirror system formed in a very narrow diamond shape, the image produced is of two mandalas, and virtually everyone's first response is that the interior images look like fireworks. The body is made of stained glass with an interchangeable exterior wand containing micro beads and tiny reflective shapes in oil.

It is also available in a variety of body/wand color combinations in three sizes. The body itself is 8" long, and the total kaleidoscope is 8-3/4" long x 6-1/4" wide (including the wand) x 3/4" thick. 

You can also purchase additional wands to make this Yin Yang interchangeable - Extra Wands for Wand Kaleidoscopes.
