Dog Disc (Fastback) Super Flex (for winter) - set of 10. Although there is a misprint, the disc itself is a genuine product made by D.T.W. Diameter: 23.5cm Color: Light Blue This disc doesn't harden in winter and is less likely to break. Because it's made softer than the summer version, it's also recommended for dogs with weak biting strength and puppies. Although it's new and unused, there are minor scratches and warping from storage. Please understand that this is a home-stored item, and only purchase if you can accept this. It will be shipped directly in a cardboard box. Also, as I have pets, please be careful if you have allergies or are overly sensitive. Thank you.
