The crystal cup body is made of high-grade crystal glass and processed with high skill. It adopts high temperature firing process of 640 °C to reach the critical point of melting of crystal glass. It is transparent, pure and non-toxic, and adopts annealing process to ensure the cup body can It is subjected to the instantaneous change of cold and heat, explosion-proof and anti-cracking, no tail vacuum, high transparency, strong crystal feeling and wear resistance. It is crystal clear, elegant and generous. At the same time, the double-layer glass structure has certain cooling and heat-preserving effects; the cup mouth is polished and smoothed by a special process, and the taste is comfortable when drinking; the use is more convenient, the design is more reasonable, and the humanization is more humanized.
