Celluloid is a top - choice material for guitar picks today. It comes in numerous shapes, colors, and thicknesses. This man - made material, first introduced in the early 1900s as a substitute for natural tortoise shell picks, offers a natural feel and a warm, rich tone. These picks have a standard shape that gives you a traditional and comfortable playing experience. Each pack contains 10 picks, and they have a heavy thickness of 1.0mm, made from classic celluloid.

Using these D'Addario guitar picks is easy. Simply hold the pick between your thumb and index finger, and start strumming or picking the strings of your guitar. They are great for both rhythm and lead playing. When it comes to maintenance, keep them away from extreme heat and direct sunlight as celluloid can be affected by high temperatures. Also, avoid bending them too forcefully to prevent breakage. If they get dirty, you can gently wipe them with a soft, dry cloth. Remember to store them in a cool, dry place to keep them in good condition for a long time.
