WOO! made an invincible flipping weight that will change the way you flip forever. The NEVER CHIP series is exactly what it sounds like. These weights will never chip. Ever. Instead of painting them black, WOO! uses a patented process so they get black and stay black. Forever. Also, there's no more guessing what size you're throwing because it's stamped right into the weight. Drag them over rocks, bounce them off docks, heck you can ever hit them with a hammer or put them in a blender. They'll NEVER CHIP. And since they will never chip, fade or lose their color... one pack will last until you lose them!
