Knob

The image shows three pink and clear glass objects. Two pink glass objects are on the left side, both are spherical but not perfect spheres. The one on the left is smaller than the one on the right. The third object is on the right side, it has a clear glass base that tapers to a narrow neck and then flares out to a larger rounded top. The top of the object is pink glass and is rounded. The background is dark gray. The title of the image is "Knob by Reading Artistic Glass Works".
