Sukumo Indigo Mini Kit
Authentic Japanese Indigo from Tokushima – Starter Fermentation Vat Kit

In collaboration with a traditional indigo farmer in Tokushima, this kit brings authentic Japanese sukumo to North America. Designed as a beginner-friendly introduction to natural fermentation dyeing, the Sukumo Mini Kit allows you to learn to grow and maintain a healthy indigo vat before committing to a larger setup.

Shell Lime Powder – Regulates the vat’s pH and supplies minerals to support fermentation.

Wheat Bran – Provides sugars that fuel bacterial activity during the fermentation process.
