title: Pilot Hi-Tec-C Coleto summary: >- A pen you assemble yourself from whichever refills you want. Four colours, one barrel, and the quiet pleasure of a thing that expects you to have opinions. pubDate: 2026-07-28 kind: object creator: Pilot year: 2007 rating: 4 tags: - stationery

The body is empty when you buy it. You choose the refills, 0.3 or 0.4 mm, in about fifteen colours, and click up to four into the barrel yourself.

This sounds like a gimmick and is not. It means the pen in my bag holds exactly the four colours I use and none of the ones I do not, and when one runs out I replace that one rather than throwing away a working pen because a colour I never touch has dried up.

The ink is the usual Hi-Tec-C: very fine, very wet, slightly scratchy on cheap paper, exceptional on good paper. It will bleed through a thin notebook. Buy better paper.

One real flaw: the clip is brittle plastic and mine has snapped twice. Buy the metal-barrel version if you can find it.
