This is "Grace", a glass handheld kaleidoscope by artist, Mai Kajiwora. These scopes come in green and silver and they measure 6-1/8"L x 1-5/8" in diameter. They have a fluid-filled, non-turning object cell and a modified 3-mirror system. The object cells include small beads and birefringent material. The images in these scopes are fantastic, brilliant, delicate and colorful but difficult to capture in photographs.
