The MIP Gen 2 Nut Drivers retain their color-coded rings for easy identification, but now feature laser-etched size markings that are precise and highly visible. Additionally, each Nut Driver is now coated with Black Oxide instead of Nickel Plating, greatly increasing its durability and safeguarding it against scratches, rust, and the typical wear and tear of RC use. Your MIP Nut Driver will maintain its like-new appearance and performance for an extended period of time.
