Since only one pen can be attached to the
Hasamu A4, many people think that a multifunction pen would be convenient. However, most multifunction pen refills are the small and thin D1 (4C for Zebra) standard. The writing distance is only a few dozen meters with water-based gel ink to several hundred meters with oil-based ink. For example, Mitsubishi's Jetstream 0.7mm has a range of 200 m. If used on a daily basis, frequent replacement is inevitable and not cost-effective.
On the other hand, Caran d'Ache 849's Goliath lead has a writing distance of 8,000 m. Even if you write 2 m every day, the ink will not run out for more than 10 years. It is also cost-effective.
For this reason, we recommend that you use the single-function pen for daily use and limit the use of the multifunction pen to when you are out and about without carrying a pen case.
