Caran d'Ache engineered these pastels to solve the permanence problem that's plagued the medium for generations. NEOART 6901 meets ASTM D-6901 archival standards, ensuring your work maintains color integrity for a century, a genuine breakthrough for artists who've watched pastel pieces fade or required UV-protected framing. The hybrid formulation merges wax softness with oil richness, producing a texture that glides smoothly across paper while building substantial color layers without the crumbling and dust that frustrates traditional pastel work.

High pigment concentration delivers intense, vibrant color that covers evenly, whether you're establishing bold color planes or layering subtle transitions. The silky finish resists the chalky, fragile surface typical of conventional pastels. Octagonal barrels prevent rolling and provide comfortable grip during extended sessions, while removable anthracite labels clearly indicate color names and individual lightfastness ratings without obscuring the pastel itself.

Professionals working on permanent pieces, students building archival portfolios, and plein air artists creating spontaneous field studies all benefit from media that finally combines pastel's immediacy with genuine longevity. No protective fixatives required, no compromises on handling qualities, just responsive, permanent color that performs now and endures decades later.
