Ink Review - Robert Oster Signature - Khakhi

Robert Oster Signature Khakhi ink is an unusually coloured yellowish green/brown ink. I found it difficult to match up the colour with other inks in my collection.

Khakhi flowed well through my Lamy pens although it felt slightly dry and when writing across the page I heard and felt a bit more feedback than I felt when writing with other Robert Oster inks. Khaki does exhibit some very nice shading.

I didn’t notice any skips or hard starts when I put the uncapped pen down to do swab tests, dry times and water resistance. Nor did I see any feathering on the papers I wrote on. 

Robert Oster inks come in 50ml plastic bottles that are quite tall making it easy to fill fountain pens from, but they are quite easy to tip over so I usually place mine in a wide, squat, glass pot when I open it. They have good identification labels on the tops of the bottles making it easy to pick out the one you want when they are grouped together.

  • Start-up: Immediate.
  • Nib Dry-out: Not noticed.
  • Nib Creep / “Crud”: Not seen.
  • Show through/ Bleed through: Showed through slightly on some papers but I could still write on the reverse of all of them.
  • Staining (pen): Not seen after several days - easy clean-up.
  • Staining (hands): My hands were clean after one wash
  • Clogging: Not seen.
  • Water resistance: Not sold as waterproof and water resistance is very low.
