TopLite team has a very professional R&D team who dedicate themselves to creativity, innovation and quality. We strictly select those to be our raw material suppliers. Before the raw materials being made into products, our QC team will carefully check the quality in order all raw materials could reach the standard. After the manufacturing, the QC team will once again test the products to check whether they are qualified to be TopLite products, which greatly ensures every product that customers received is of excellent performance and great quality.
