Overview

Muji makes this fountain pen with an aluminum body and black ink, produced in Japan. The listing is brief and does not describe the nib, the filling system or the grip.

An aluminum body and plain black ink suit a simple desk pen. Without nib size or refill details, it is hard to judge how it writes or how to replenish it.

Who it's for

A stationery fan after a minimalist metal pen may like the aluminum body. Anyone who needs to know the nib, cartridge type or weight should check the manufacturer's information.

Performance notes

Writing quality depends on the nib and the ink feed, and neither is described in the listing. The aluminum barrel is the only construction detail given.
