Classical celluloid picks are made from the highest quality celluloid material and their main feature is flexibility and durability. They comes in tortoise shell, multicolor, black, white, blue, vintage and white MOP, in standard teardrop shape and in 4 gauges: Thin, Medium, Heavy, Extra-Heavy. The celluloid material sounds fantastic on the strings, is one of the original guitar pick materials and still a favorite today. Introduced in 1900’s, the tortoise shell version replaced the natural tortoise shell picks which became illegal.
