The Do-It Egg Sinker Mold Assorted allows you to slip by your fish undetected. The line will slip through Egg or Slip sinker, so the fish will not feel the weight of the sinker when it picks up the bait. The hook settles more quickly without the sinkers resistance. Plus, the fish cant use the sinkers weight to help throw the hook when breaking water. This fish wont be the one that got away. Comes in sizes 1/8 ounces and 1/4 ounces.
