The World's Smallest Imperial is a yo-yo produced by Duncan. It is quite simply, a much smaller variant of the best-selling Imperial. The yo-yo was produced in collaboration with toy manufacturer Super Impulse as part of their World's Smallest toy range. This miniature Imperial performs much like its larger counterpart and is available in the same red, green and blue colors. The throw is recommended for ages six and up and thus comes stock equipped with a shorter string. However, the string can be replaced with any standard length.
