"So that's how you throw," is what you'll stay after throwing the Innova Champion Leopard. Factory Second discs are discounted because they have minor blemishes and/or multiple stamps. They perform the same as stock discs.

These discs may contain bubbles or flecks in the plastic, other cosmetic imperfections, and/or multiple stamps.
