Muji 0.5mm Retractable Gel Pen

This gel ink pen has a quick-drying, water-based ink that creates a smooth universal writing or sketching experience whether you're left or right-handed, and prevents bleed-through on paper. It also has a built-in mechanism to prevent ink from drying out or flowing incorrectly. The pen has a clip for easy storage in a pocket, lanyard, or closed notebook, making it perfect for on-the-go use.
