Shinsan Amber

This bottle is about 80% full. I’ve used it periodically throughout the years but it’s time it found a new home. The swatch card in the photos was done in the past week.

Bright, rich, and full of character — Shinsan “Amber” by Manganeko Inc. captures the luminous warmth of polished resin and autumn sunlight. This Japanese-made fountain pen ink offers a smooth, consistent flow with excellent shading potential, especially in broader nibs or when used for calligraphy.

The elegant 50 mL glass bottle features clean lines and a wide base for easy pen refilling, blending modern design with traditional ink-making craftsmanship.
