This is probably the most elegant one-piece top that Rich has ever created. They feature the donut shape of a torus for the main body of the top and flow beautifully right up into the stem. Smooth, flowing, flawless metal that spins BEAUTIFULLY! Rich also added a bearing to the top of the stem on these so that you can spin them upside down! Really a wonderful top, very fun to spin, with good solid spin times - I've gotten times as long as 12 minutes with mine. These tops were made in 2016 and are 1.19" in diameter.
