These have a fluid-filled, turning end object chamber with a black background. These scopes measure8-1/2"T x 2-1/2" in diameter at the object cell end. Each of these scopes is signed and dated by the artist. Please call the store prior to ordering one of these scopes to determine which colors we currently have available.
