Opa has made tops, Yo-Yos, and Kaleidoscopes. Inventory varies based on how much time he has available to devote to these items. Occasionally, some of the higher-end, more complex items come up for sale on my Etsy Site.
Opa quite often is questioned on exactly how to spin a top like the one pictured to the right. To help answer that question he has prepared a You-Tube Video on how to spin a self-winding top - click here for a You-Tube Video (opens in a new window).
