A disc golf scorecard is provided that not only allows the recording of scores for each hole of one or more rounds of disc golf for one or more players but also is shaped in the form of a disc for storing or carrying within the cavity of a disc or its carrying bag. The sequence includes the sequence of: 1) treating with an HF solution; 2) treating with pure H2SO4; 3) treating with an H2O2 solution; 4) a DI water rinse; and 5) treatment with an HCl solution. A blend of thermoplastic elastomer and polypropylene is used to impart added flexibility to the head.
