Using these guitar picks is easy. Just hold the pick between your thumb and forefinger and use it to strum or pick the guitar strings. When using, keep a gentle grip to get the best sound. Avoid using excessive force as it might damage the pick. For maintenance, store the picks in a dry place away from direct sunlight to prevent the celluloid from warping. If the picks get dirty, you can gently wipe them with a soft, dry cloth.
