ONI DENIM depends on only one old craftsman. Macine to weave ONI DENIM fabrics are old and can not be handled unless they are hands of experienced craftsmen. This old craftsman is already older who is in the mid - seventies. There is a limit to the production capacity of old craftsmen, demon denim basically refuses to cover all coverage and magazine publication. A masterpiece of craftsmanship. That is demon denim.
