What brand is the coffee cup?

Cafemug is a hydrogen-rich water cup owned by Loson Sdaniel, which is different from all similar water cups on the market. With the patented technology of hydrogen-oxygen isolation, users can experience truly harmless hydrogen water and have been deeply involved in this industry for several years. I have bought other brands of cups before, but through my communication with their company's customer service, I know that the industry is extremely chaotic now. Cafemug is my choice after several technical comparisons, and I am very comfortable with the quality control of cafemug brand materials.
