Thick graphite blocks transform into wash effects when you add water. Pacific Arc Jumbo Watersoluble Graphite Sticks measure 7/16" × 4¾", substantial enough to cover large areas quickly while maintaining control for detailed passages. The chunky format feels solid in hand during extended drawing sessions, whether you're laying down dry tones or working wet-on-wet.

High-quality graphite formulation dissolves smoothly when activated with water, creating atmospheric washes from bold linework. Sketch dry on your paper surface, then brush over with water to melt edges and build tonal gradations. Or dampen the stick itself and draw directly onto wet or dry paper for immediate wash effects. The thick body withstands vigorous application without crumbling, from aggressive mark-making to gentle shading.

Choose Medium Set (2B, 4B, 6B) for controlled tonal work and preliminary studies. Soft Set (8B, 10B, 12B) delivers rich darks and dramatic contrast, ideal for expressive work where deep values matter. Both sets enable quick coverage in landscape studies, figure drawing, and exploratory sketches where graphite's versatility meets watercolor's fluidity.
