After temporary deformation, the tip always returns to its original shape. This allows you to draw both thin and thick lines (from 1 mm to 3.25 cm). Water-based ink. Bright, intense colors. Ventilated cap. Milan markers meet European and American safety standards. They contain no phthalates, heavy metals, or other toxic substances. They are safe for children.
