Fantastic ink. Not an exact match for any other ink in my collection. Brighter and blue-er than Pilot Ku-Jaku which is probably the closest I have. Much brighter than Yama Dori. It does have a lovely reddish-copper sheen, but it’s not super heavy. Opaque and readable on the page, excellent flow, not quite as syrupy-textured as some of the darker Sailors (Kikyou in particular) but very smooth and lovely.
