These discs are packaged in kits to promote youth ultimate. We are providing discs individully at a discounted price to help get good discs in the hands of youth players. Also available in bulk discounts. Produced a few years ago in conjunction with the then UPA (Ultimate Players Association) these discs each have a unique skill depicted on the print of the disc. The are also sold in complete packages with each of the different skills and work great as a school or coach package for younger ultimate players not able to handle the full sized 175 Gram Ultimate discs. These discs fly great and provide an excellent starting step for kids in elementary school or younger.
