By dyeing repeatedly, indigo penetrates deep into the fibers and makes the cloth and threads stronger. Aizen has excellent antibacterial and bactericidal effects, so it has been useful as clothing and daily life cloth. * When wearing white or light-colored shoes, it is recommended to wash them about 3 times first. The indigo color that does not adhere to the fibers and the lye come out and calm down. -About washing- Unlike Indian indigo, natural indigo hardly transfers color even when washed. However, at first, please wash separately until the color settles down. If the color is transferred to the one washed with the deep indigo, it will naturally fade. Please dry in the shade when you dry. ○ We use yarn that has acquired organic cotton certification by Avanti Co., Ltd. ○ When washing, we recommend that you put it on the net. 〇 A family sticker from the Organic Cotton Association [JOCA] is attached. -Explanation of JOCA Family Seal- Based on the JOCA Charter, this product shows that JOCA member companies aiming to popularize organic cotton products made it in a way that considers people and the environment, making the best use of Japanese technology and sensibility.
