Sennelier shapes each pastel stick by hand using the same careful process they've refined since 1900. That traditional approach produces pastels with exceptional softness, pigment releases under minimal pressure, allowing you to build luminous color without forcing strokes or abrading paper surfaces. High pigment concentration means even light touches deliver saturated, opaque color rather than dusty translucence.

These half-stick formats balance economy with usability. You get substantial working material while the shorter length provides better control during detailed passages. Water solubility adds versatility; dampen finished areas to create wash effects or blend colors into smooth transitions that pure dry work can't achieve. The pastels maintain their softness whether used dry or activated with water, responding consistently across techniques.

The 20-color set covers essential primaries and earth tones, viridians, yellows, blues, and reds spanning warm and cool variants, enough range for complete compositions without overwhelming beginners. The 40-color set expands into nuanced tonal variations: multiple values of lemon yellow, violet purple, viridian, and cobalt blue provide subtle gradations that eliminate constant blending. Both sets include ivory black and white for value control. Curated selections eliminate redundancy while ensuring you have colors that actually work together rather than arbitrary rainbow assortments.
