All of these tops have a matching base – on some the top fits like a box lid (if the diameter of the blank allows for this), and others have the stem fitting into a hole. All the bases have a slight concave surface turned on the underside to spin the top if desired. All are decorated with a chatter tool and knurling tool then colored with a variety of pens and paints.
