Following numerous tests, the process is finally optimized in an in-house laboratory and scaled up to an industrial level. This modern nanai leather now undergoes a totally new, environmentally friendly, multi-stage process. Years of research and highly advanced technologies help retain the pigmentation and unique texture of the salmon skin. This sows the seed for the birth of the company, nanai.
