About
A minimalist everyday pen for people who care about materials, balance, and feel. MUJI’s Aluminium Knock-Type Ballpoint Pen brings a clean silhouette with brushed metal that looks sharp on any desk while staying light in hand.
The 0.5 mm tip lays down precise, consistent lines with low smudge, making it great for notes, signatures, and journaling. The knock mechanism feels tight and confident, with metal fittings that don’t rattle over time. It’s refillable with gel ink in blue, black, or red, so you keep the body and swap the core, which is both practical and sustainable.
Dimensions are compact and pocket friendly, and the smooth aluminium grip avoids fatigue on longer sessions. This is a small upgrade that quietly improves your everyday carry and workspace aesthetic.
