The Caran d’Ache Fibralo Brush Pen in Cobalt Blue (186.160) is a water‑soluble, fibre‑tipped brush pen offering expressive versatility. Its flexible brush tip delivers dynamic strokes ranging from fine 0.5 mm lines to bold 5 mm marks—and springs back to shape with ease. The ink is bright, transparent, and food‑colour based, ensuring vibrant washes that don’t bleed through paper and wash out from most modern fabrics. Crafted for sketching, colouring, calligraphy, comics, mixed media, stencilling, transfer printing, and watercolor techniques, this pen encourages creative experimentation with both precision and fluidity. It’s washable, non-toxic, and crafted to meet the high standards of artistic performance.
