Using these guitar picks is a breeze. Just hold the pick between your thumb and index finger and start strumming or picking your guitar strings. For best results, use the thin picks for a bright and crisp sound, medium picks for a balanced tone, and heavy picks for a more powerful and full - bodied sound. When not in use, keep the picks in the collectible tin to protect them from damage. Avoid exposing the picks to extreme heat or moisture as this can warp the celluloid material. If the picks get dirty, you can gently wipe them with a soft, dry cloth. Enjoy playing with these awesome vintage - style picks!
