D'Addario 5CSH4 single Thumb Pick medium

The D'Addario 5CSH4 is a medium-size, shell-colored thumb pick produced from the highest quality celluloid.

Celluloid is one of the most popular guitar pick materials today. It's available in a wide variety of shapes, colors and thicknesses, and provides a natural feel and warm, fat tone. A man-made material, celluloid was first introduced in the early 1900's as a substitute for natural tortoise shell picks.
