Dog Discs Winter set of 10 discs. 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 and puppies. I'm sorry, but I cannot accommodate combined purchases or splitting the set. Although they are new and unused, there may be minor scratches or warping from storage. Please purchase only if you understand that they have been stored at home. They will be shipped directly in a cardboard box. Frisbee Dog Sports
