Sennelier uses only the purest pigments, mixed with minimal amounts of natural binders, in an exclusive formula that yields lightfast, water-soluble pastels. There is just enough binder to hold the pigment together as the pastels are formed by hand, placed in special molds, and allowed to air dry. No fillers or clays are used. Sennelier soft pastels are highly concentrated and so soft that a gentle stroke will deliver a solid, powerful line of brilliant color. Full Sticks are 2½" long × ½" in diameter (64 mm × 13 mm) and half sticks measures 1-1/4" long x 1/2" in diameter (32 mm x 13 mm).
