Dog Disc (Fastback) Super Flex (for Winter) - Set of 10 Although there's a misprint, the disc itself is a genuine D.T.W. product. Diameter: 23.5cm Color: Light Purple (looks almost white, like milky white) This disc doesn't harden in winter and is less likely to crack. It's made softer than the summer version, so it's also recommended for dogs with weak biting strength and puppies. This is a set of 10, but up to 50 discs can be sold. If you'd like more, please comment. Although it's new and unused, there may be minor scratches and warping from storage. Please understand that this is a home-stored item, so please purchase only if you understand. It will be shipped directly in a cardboard box. Also, please be aware that I have pets, so those with allergies or those who are overly sensitive should take caution. Thank you.
