SanyMuCos focuses on the design and development as well as production of cosplay costumes for more than ten years. In 2013, when the cosplay clothing industry was in its hundredth year, my family received some request information to help cosplayers who couldn't buy clothes to make clothes to their liking. I was in charge of sales, design, and sewing together with my mother, who is quite a careful and conscientious person, and she was solely responsible for the quality control, ironing, and packaging of the clothes. Our costumes got a bunch of good comments from cos fans, and in June of that year, SanyMuCos was established. In 2014, we contacted "Monthly Girl Anime" and developed its derivatives, and the sales number was relatively satisfactory at that time. In 2015, we embarked on the development of "The End of the Killing Angel", a product with a high degree of complexity and difficulty that had to rely on the factory production system, as well as the previous production pressure problem. This was also a turning point in my life. In September of the same year, we built a 109-square-foot cosplay clothing production plant. In the same year, the SANYMUCOS brand was established, accounting for 90% of the increase in-store sales. In 2017, our sales entered the top three in the Chinese market, and the factory slowly expanded to more than 300 people. We have established Wuhan Animation R&D and Design Studio, established a mature design operation and R&D team, established cooperative relations with more COS team partners, and competed in the Chinese market step by step. We will become more professional, just for better service and better work.
