Refilling Noblesse Oblige Mechanical Pencil

The montblanc-pencils/index.html">Mont Blanc mechanical pencil has its own proprietary erasers and pencil leads. Take, for example, the Mont Blanc Noblesse Oblige pencil. The Noblesse Oblige Montblanc pencils (which come in both platinum and gold trim) accept the .7 mm pencil leads, which are sold in packs of 50. Pencil leads can be stored in a cool, dry place for years. Erasers, however, dry out, so when refilling your Mont Blanc pencils, be sure to regularly refill the erasers. Montblanc erasers come in a refill pack of 10.
