・Set includes: 3 types of varying hardness (Thin (0.5mm), Medium (0.75mm), Heavy (1.0mm)), 3 picks of each, for a total of 9 picks. ・Shape: Triangle. A popular shape. You can pick with the same feel from any of the 3 points, so it's okay if one gets chipped. Relatively suited for chord strumming and cutting. ・Material: Celluloid. A standard, basic material. A slight disadvantage is that it's prone to cracking, but it's easy to use without any quirks, and the tone is also standard. ・Thickness: Thin (0.5mm): Suitable for acoustic guitar strumming. Because it's soft, the volume is low, and it produces a bright, light tone. Not suitable for solos or rock because of the weak picking. Medium (0.75mm): A standard thickness that is widely usable. With moderate flexibility, the tone is well-balanced, and it's a versatile player that's easy to use from acoustic to electric guitars, for strumming and solo playing. Heavy (1.0mm): Suitable for live acoustic guitar performances when you want to produce a loud sound, or for rock-style playing. ・Colors will be random. Please understand.
