Using these Fender Offset Guitar Picks is easy. Just hold the pick between your thumb and forefinger, with your thumb resting on the contoured imprint. Then start strumming or picking your guitar strings as you normally would. When it comes to maintenance, keep them away from extreme heat or sharp objects that could damage the polycarbonate material. You can clean them with a soft, dry cloth if they get dirty. Also, make sure to store them in a safe place, like a pick case, to prevent them from getting lost or bent. With proper care, these picks will last you a long time and keep enhancing your guitar - playing experience.
