These lips are manufactured to the highest quality and tolerance standard Diamond Tackle is known for. Since they are stamped and pressed into shape (not bent by hand), the lips are all exactly alike. This quality control ensures your plugs will swim exactly the same from one batch to the next.
Unlike some very inferior copies on the market Diamond Tackle Lips are HIGHLY POLISHED TO ELIMINATE ALL BURRS which can and will cut your line. Nothing worse than losing a custom made plug because of a razor edge burr. When you choose Diamond Tackle you choose quality and your finished product will clearly reflect it. Compare them and see for yourself.
