Esteemed for its versatility across playing styles, the Standard 351 Casein Pick is available in a familiar shape, but with distinctive qualities: the playing edge has a right-handed bevel to help it glide along the strings, plus a pointed tip for the perfect balance of strumming and articulation.

Casein guitar picks are crafted from organic materials that are sensitive to environmental conditions, particularly dry weather. While these picks offer a unique, natural feel, exposure to prolonged dry conditions may affect their performance and durability. Storing Casein picks in a controlled environment with moderate humidity levels may help prevent drying, warping, and/or cracking. D'Addario recommends storing your Casein pick with a Humidipak as an easy and convenient method of keeping your picks hydrated.
