Uni-ball Signo UM-151 Gel Ink Pen - 0.38 mm - 10 Color Set (japan import) (Office Supplies)
is a Korean friend who introduced me to these markers. She told me that she bought in Korea because they were my expensive than in Japan. It may sound incredible, but the price is still cheaper on Amaon plus they arrive in Japan within 15 days. Bravo
