Quanzhou Chengfeng Hardware Factory is a company that cooperates with foreign trade and specializes in producing well-known "Butterfly" brand collar hooks, key rings, pants buttons, and pins and other small hardware products. Since the establishment of the new factory in 2006, with the efforts of our research and development team, we have developed many new products. We have a variety of copper, stainless steel, and iron plated products, and can produce collar hook products with various specifications from 00 to 12. In recent years, with the further intensification of market competition, we are deeply aware that the survival of the enterprise is facing a crisis. In such an environment, we must either advance or retreat. Therefore, we will diversify our business and enter the bra hook industry. So far, our production has begun to take shape and can process polyester, nylon, cotton, and other types of fabrics and stainless steel wire, coated wire, and so on.
