I bought a Platinum Carbon's pen. The price is interesting. No problem if you lose the pen. Just buy another one. I highly recommend this product to all fans of sketching . Even the Carbon's ink is excellent. You can paint on it with watercolors without you remove it. No smudges. It dries quickly on watercolor paper and plain paper. Fantastic nib ! The line is very thin, just like my 0,25 rapidograph. No problem whit write direction. Smooth and pleasant. Finally ... the product I am looking for years. Thank you.
