Two types of indigo dyeing and kakishibu dyeing are available.

Kakishibu dyeing is so-called persimmon tannin dyeing.

Both indigo and kakishibu dyeing are traditional Japanese fermentation processes. These duvet covers are made only from plant-derived materials: linen, cotton, indigo, and kakishibu. Because it is something that touches the skin, the peace of mind of natural origin invites a comfortable sleep.
