One of the primary models in the Hi-Ker line. The Professional Top was made with the same blanks as the older Cheerios. Most original Cheerios are slightly oversized, like this yo-yo, at 2 3/8" Diameter. Some later versions may have been made by Duncan, after buying Cheerio, as they are the same shape and size as the Duncan models of that time.
This an older Professional Top, in an unusual color combination. Mint condition, with excellent logo.
