Each half stick measures 1-1/4" long x 1/2" in diameter. 

These pastels are comfortable to hold and allow for large areas to be covered with a lush, luxurious color. Each pastel is composed of high quality pure pigment and a natural transparent binder. The exceptional brightness is the result of the pigment and the natural mineral fines discovered by Sennelier in 1905 and that have been used ever since.
