Lyra Polycrayons Soft 12 provides artists with twelve square-shaped, professional-grade soft pastel sticks boasting an exceptionally high pigment concentration. Ideal for the smudge technique and blending, their light-resistant chalk cores allow you to use the sharp edges for crisp line work or the flat sides for sweeping background shading. This versatile assortment can even be dissolved with a wet brush to produce beautiful watercolor effects on multiple paper surfaces.
