Up for auction is an exceptional collection of 13 Duncan yo-yos and related accessories, measuring 5 1/2 x 5 1/2 x 1 1/2 inches each. This lot includes a variety of items such as the Duncan Butterfly Yo-Yo in original packaging (4 pieces), Duncan Satellite Lighted Yo-Yo (3 pieces), Duncan Imperial Yo-Yo (1 piece), two packs of Duncan Yo-Yo Wax with replacement strings, and both a loose Whistling Yo-Yo and Yo-Yo top. While the yo-yos in original packages appear unused, they do show some wear from age.
