Dog Discs Winter set of 10. Although there's a misprint, the discs themselves are genuine D.T.W. brand products. Diameter: 23.5cm Colors are as shown in the photos. These discs won't harden or crack in winter. They are softer than summer discs, making them suitable for dogs with weaker bites or puppies. Sorry, but I cannot accommodate combined or individual sales. Although new and unused, there may be minor scratches or warping from storage. Please only purchase if you understand that these have been stored at home. They will be shipped directly in a cardboard box. Frisbee Dog Sports
