about Us

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.

Our Quality Commitment

"Master Sun's Private Collection" is a collaborative brand series under our brand, showcasing versatile and uniquely designed products that reflect our years of collecting resources in foreign trade. We have added our own design elements and leveraged the expertise gained from years of collaboration with foreign manufacturing factories. These products are individually customized by a few master craftsmen, offering quality comparable to the originals. Many intricate details and textures are rarely seen in the market. Our principle is to provide top-notch quality, innovative design, and valuable products. In short, only products meeting the standards of physical stores priced at $1000 or above are showcased for sale. Our store accepts returns within seven days without any reason. In fact, some customers may be unsure which style suits them best, so they can try around three different styles and return the ones that are not suitable. However, custom lenses cannot be returned. With our years of lens fitting experience and professional equipment in physical stores, we can accurately measure and ensure that the lenses meet international standards before shipping. Additionally, all branded products with anti-counterfeiting measures come with their respective verification seals. Only master craftsmen who have worked in Master Sun's studio for more than eight years are eligible to participate in the assembly process to guarantee the precision of the lenses.
