Since the advent of Swiss diamond drilling pot, it has innovated the extremely hard nano-patented coating technology of real diamond-mixing and casting real diamond crystals and nano-materials on the surface of the pot body, thus ensuring that the product has excellent non-stickiness, super corrosion resistance and wear resistance, and excellent thermal conductivity. This patented technology won the gold medal at the Geneva International Invention Exhibition that year. The Swiss government licensed Swiss diamond products to use the national flag as a trademark, so it was praised as Rolls Royce in cookware by The Wall Street Journal. As the official designated gift of American Emmy Award and Golden Globe Award, it is loved by chefs and housewives all over the world and selected as the most recommended cooker brand by many authoritative organizations.
