1.4mm, Single Pack

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.
