Immerse your writing in a clear summer sky with Sailor Shikiori Fountain Pen Ink 20 ml – Souten. Souten (蒼天) is azure heaven — the blue of a high, open day in summer — one of Sailor’s Shikiori dyes, the line that weaves Japan’s seasons onto the page.
On the paper it is a clean, readable blue: not navy, not ice, a sky you can still see through. It is a water-based dye, made to flow smoothly and stay gentle on fountain-pen feeds — not water-resistant.
Housed in Sailor’s square 20 ml glass bottle, it is a small seasonal bottle for journals, letters and anyone who wants summer air on the nib rather than a house black.
