You want a blue that's not sky, not navy, not 'blue-ish.' Delft Blue 29 is that specific, confident shade. The Procolour core holds a strong point, lays down with the covering power of wax and the glide of oil, and finishes clean without smudging your next line. Round barrel means your hand stays comfortable through long sessions. Add it to your cart and draw in the blue you actually see
