The Joy of Fountain Pens

When UC Berkeley professor David Eisenbud visited the University of Tokyo some years ago, one of the Japanese professors told him they have better chalk than their American counterparts. “Oh go on, chalk is chalk,” Eisenbud said incredulously. As it turns out, chalk isn’t just chalk. Many of the brightest mathematicians on the planet believe that Hagoromo Fulltouch is mystical in some way. They say it can’t break. They say it glows on the board. They say it inspires and invigors, while also leaving a cleaner, smoother, and more elegant line. “The legend is that it’s impossible to write a false theorem with this chalk,” says Eisenbud, now a convert.
At first, Hagoromo Fulltouch was only available in Japan, which meant if you wanted a stick, you had to proxy it like streetwear. That was until an Amazon distributor started selling Fulltouch to American professors, which is how the chalk wound up in so many U.S. math departments. Five years ago, however, Hagoromo president Takayasu Watanabe announced the company would be halting production in February of 2015, and stop sales altogether the following month. American mathematicians went crazy. They bought, hoarded, and stockpiled as much of the stuff as they could. Eisenbud estimates he has a ten-year supply at home.
Soon after the company shuttered, a secondary market emerged. “I didn’t want to become a chalk dealer,” laughs Max Lieblich, a math professor at the University of Washington. “But I did like the idea that I could be the ‘first stick is free’ chalk dealer in my department.” Those who stockpiled the chalk sold sticks to their chalk-less colleagues, presumably at hiked up prices, much like rare and coveted Nikes. But the market came crashing down a year later when a South Korean company bought rights to the formula and started reproducing the “Rolls Royce of chalk” faithfully. Today, you buy Hagoromo Fulltouch in white and a variety of colors on Amazon.
