We are frequently asked why Henri Roche pastels are so expensive. Its pretty simple, Henri Roche pastel sticks are virtually pure pigment sticks. You will find that Henri Roche pastels are very unique in color, texture and feel. Henri Roche pastels are formulated with pumice, which allows for a greater concentration of pigment then most pastels. Other brands of pastels start out as a batch of white chalk; to which pigment is added. Henri Roche pastels however start as a batch of pure pigment, to which pumice and a tiny bit of binder are added, so you are actual painting with pure, unadulterated, saturated pigments.
