The Flipover Top (sometimes called Tippe Top, Pop Top, Reversing Top, Turn Around Top, and Upside Down Top) is a unique kind of top that flips over onto it's stem while it's spinning. You start it spinning like any other top, but because of it's shape, weight distribution, and friction, it can't help but flip over. This type of top will travel a lot. I recommend using it with a concave Spinning Tray, such as the one we sell, which keeps it in one spot and lets you enjoy this unique toy more easily. There are two styles, Red and Natural. The red flipover tops have a red body and natural wood stem. The natural colored flipover tops are all natural wood color. You can paint or stain them, making them a toy and a craft project. Diameter = 1 1/4 inches (32 mm) , Height 1 3/4 inches (44 mm).
