aun is the Japanese word for "om," the Sanskrit meditation mantra. The founder of aun is Akihiro Eda and the studio is located in Kurashiki. aun's glass pens are all handmade and designed by aun's team of three artisans. The nibs are ground to 7 sizes, ranging from EF to C, which requires finishing each nib with 8 gradations of sandpaper, taking about 1 hour to grind each nib. Finally, each nib is inspected under a microscope to ensure the capillaries along each nib are even for smooth ink flow to the paper.
