Dog Discs (Fastback) Summer set of 12 discs. Although there is a misprint, the disc itself is a genuine product made by D.T.W. Diameter: 23.5cm Colors: Red, Orange, Pink, Purple (3 of each) These are for summer use. They may be more prone to cracking in cold weather, so please be careful. They are less likely to crack if used for throwing practice or during the warmer hours of the day. Although they are new and unused, there may be minor scratches and warping from storage. Please understand that these are items stored at home by an amateur, and only purchase if you are comfortable with this. They will be shipped directly in a cardboard box. Also, I have pets, so please be cautious if you have allergies or are overly sensitive. Thank you.
