A 30mL bottle of Octopus’s Sea Serpent (blue) fountain pen ink, with a stunning multi-color sheening effect.
Where it fits in:
Octopus fluids is an underrated German ink maker, and I adore their inks — this sheening line is just as striking as the most famous sheening inks currently available in the US (think: Diamine’s much-loved Polar Glow).
