We now sell Pengi, the original Korean spinning top toy! My son loves playing with it and so does his grandpa! We thought we share this clip of his grandpa trying to teach him how to play it.
My dad told me that he used to play this as a child and it brings back fond childhood memories. In Korea, they would play with it on ice during the winter since it would spin better on the smooth surface. The goal was to keep it spinning as long as possible....some people apparently would spin it for hours!
