This kaleidoscope was the best seller in our shops, and continues to be a best seller in our internet gallery. The fluid motion of the kaleidoscope is so lovely! You can see the fireworks immediately once you pick up the kaleidoscope. The long tube of approximately 11 inches provides a wonderful array of color for your enjoyment. An even larger tube of 13" in length and 3/4" in width can be added for even more color. Shown below.
