This is a set of Kodak CC filters. 05C, 05M, 10M, and 85 are unopened. The other filters have only been opened once or twice and are in good condition. I will send them in a case that holds 20 filters, including "05Y, 10Y, 20Y, 05M, 10M, 05C, 10C, 20C, 05R, 10R, 20R, 05G, 10G, 20G, 05B, 10B, 20B, 81A, 81C, and 85."
