Celluloid is a top - choice material for guitar picks today. It comes in various shapes, colors, and thicknesses. This man - made material, introduced in the early 1900s as a substitute for natural tortoise shell picks, offers a natural feel and a warm, rich tone. These picks feature a standard shape for traditional comfort. You'll get a pack of 10, with each pick having a 1.0mm heavy thickness and made from classic celluloid.

Using these D'Addario guitar picks is easy. Simply hold the pick between your thumb and index finger. Place it against the strings and strum or pick as you play your guitar. When using, make sure your hand is relaxed to get the best sound. As for maintenance, keep them in a dry place to prevent the celluloid from warping. Avoid exposing them to extreme heat or direct sunlight for long periods, as this can damage the material. Also, check regularly for any signs of wear and tear, and replace the picks when they start to get too worn out.
