About Us

Who We Are

In the early stages before establishing our own brand, we served as OEM partners for some Japanese and Korean design brands, focusing on handling difficult processes that others could not complete. At the same time, out of passion, we have also collected various niche boutique glasses from around the world. However, many collected glasses are accessories and contain flaws or other issues. As customer demand increased, we established the vision of creating our own domestically produced "handmade glasses", combining our years of OEM experience and collected classic styles. This led to the birth of the "Master Sun Private Collection" brand, aiming to become a century-old optical store using high-quality materials. Using "good" materials means choosing high-quality raw materials and having them processed by skilled craftsmen. This also involves using our experience and technology to improve and upgrade the construction of the glasses.
