German writing-implement company Montblanc have designed and released the Montblanc Albert Einstein Limited Edition, in honor of the German-born theoretical physicist. Limited to a production of just three thousand pieces and available exclusively in Montblanc boutiques, these pens feature several of Einstein’s formulas, including his revolutionary E=mc2. The dark blue pen cap, reminiscent of the darkness of the universe, has a grid design inspired by Einstein’s theory of relativity and contrasts well with the platinum-plated body of the pen.
