Polanik Competition Unpainted Steel Shot Put

-----THESE ARE NOT STAINLESS STEEL, they are regular STEEL------ "Some discoloration or tarnishing is normal on unpainted shot puts." The Advantage of having an UNPAINTED shot -- they are able to be manufactured with small groves in the shot. These small groves are IAAF Certified and INCREASE the Grip on the Shot. Many advanced throwers prefer to have the increase in grip.
