The Clayton NuTone ProteinGuitar Pick was created to mimic the extraordinary sound of authentic tortoiseshell. Its unique composition produces a punchy bass with clear treble tones, making it a perfect pick for acoustic play. Its natural lubrication releases off your strings quickly and gives you the ability to produce articulate tones. Made from polymerizing, an animal protein, it is much the same as the famed, but endangered, Hawksbill Sea Turtle's shell. NuTone Protein Picks replicate the sound and feel of the Hawksbill's shell with its natural protein components, but no animals are harmed in any way by its production.
