The D’Andrea USA Pro-Grip Brites picks are made from an alternative material that solves the slipping problem. Crafted with the popular delrin/acetal material, they are carefully designed and manufactured for maximum memory and minimal wear, features that defined the original turtle wax. They feature a classic 351 shape with a slightly tailored sharp tip. The striking surface of the strings offers players an alternative method of articulation and expression without sacrificing the familiar feel of the 351 shape. Available thicknesses: .50 / .60 / .73 / .88 / 1.00 / 1.21.
