MUJI Pens are made with an ink mechanism for smoother writing which also prevents the ink from leaking. They are designed for smooth and comfortable writing, making it perfect for everyday use. We redesigned our pens to make them compatible with all gel ink refills in order to reduce waste. This also allows you to customize your own pen according to your preference in color, body, ink, and thickness.
