The record.

From the registry, rebuilt from Peter's researched material cards. Boku-Undo, the same ink as MB5 in a different coloured label (Peter, 2026-09-30): synthetic resin, super concentrated, intense black with purplish-blue undertones when diluted, stable in cold. Previously recorded as a Kuretake ink; the claims that came with that identification are removed. MB5 and MB8 are one ink under two codes, so C2 and C3 share it.
