Professional insight

Stationery buyers pick KACO by refill system first. A cheap body is pointless if refills are hard to find.

  • Note the tip size: 0.5 mm is the common default.
  • Check whether refills are KACO only or standard format.
  • Fountain models may take short international cartridges.
  • Multi-color packs often mix ink types; read the list.
