Penguin Kaban-sha Original Ink Polar Night Blue Nuit

This is the second release in Penguin Kaban-sha original "First Penguins Ink" series.
Polar night is the season in Antarctica when the sun never rises, occurring from June to July around the summer solstice.
This deep blue ink is inspired by the ambiguous color of the sky.
It starts out as a vibrant ultramarine color, turning a slight ash color as it dries.
The sheen is invisible.
