Focusing on cooker safety, we tried to do some research on the real safe cooker. After our research, The Nature Series finally came out. We used elements of cobblestone as its shape, which has an eastern spirit and feeling. Titanium is a non-toxic metal. As the key technology of the product, the Micro crystal titanium has hardening capacities; therefore, it is anti-shaved and easy to clean to remove grease and diseases. Furthermore, the adhesion of food molecules can be reduced effectively because it features a fine and rolling texture. It possesses non-adhesive properties. Thus, it is advantageous compared to non-stick coating pans on the market.
