Designed by Marc Newson, Montblanc M expresses the modernity of today and the timeless elegance of tomorrow. Made of black precious resin, the writing instrument's fluid lines flow gently into one another. An innovative magnetic cap-closing mechanism automatically aligns the cap with the Montblanc emblem embedded in the “plateau” of the writing instrument. Please note this product contains magnets. Before using it, if you have any doubt about its safety, please consult your health care professional.
