『Aijō‑zome (Indigo Pellet Dyeing)』
Aijō‑zome is a novel indigo dyeing technique that uses “aijō”—the pigment obtained by fermenting and precipitating fresh indigo leaves—dissolved in water for dyeing. Unlike traditional indigo dyeing, it requires no fermentation vats and brings out the fabric’s natural, soft tones. By combining it with “bengara,” a natural red‑clay pigment, you can achieve everything from fresh sky blues to deep indigos, showcasing a stunning spectrum of hues.

『Indian Indigo』
Indian indigo is a natural dye extracted from “komatsunagi,” a leguminous plant grown in South India. From cultivation through production, every step is done by hand, resulting in a deep, vibrant blue. This carefully crafted indigo evokes the warmth and richness of nature.

『Susu‑zome (Soot Dyeing)』
A dye made from soot produced by burning pine. “Soot” is carbon formed by the incomplete combustion of organic material and serves as the base for traditional ink. We mix pine‑soot pigment with natural starch paste to create the dye. Dissolve a small amount in water, knead thoroughly, and you’ll achieve a rich, expressive black. By kneading the smoked soot into the fabric, you can enjoy its deep, layered hues.

◾️ Lead Time
Since we hand‑dye every piece after an order is placed, please allow 3–4 weeks for shipping. Delays may occur due to inclement weather or peak seasons. Thank you for your understanding.

◾️ Care Instructions
※ Each item is hand‑dyed, so slight variations in measurements, unevenness, or color tone compared to product photos may occur. We hope you enjoy these nuances as part of its charm.

※ When washing, please note the following:

1 If stains or dirt appear, rinse immediately with water or soapy water before drying, or gently blot with a damp towel or tissue. Avoid scrubbing, as this may cause color loss.

2 For machine washing, we recommend placing items in a laundry net. For hand washing, gently wash in lukewarm water with a small amount of detergent to help preserve the color.

3 To prevent color transfer, wash separately from other garments for the first few washes.
