This is an independent research and development project officially launched in January 2017. At that time, the hydrating instrument was just emerging, and even many people didn't know much about it. At that time, they wanted to design a fun and interesting product to enter the market. After the design was completed, it was delayed for nearly three months. First, they didn't understand the prospect of this category. Second, the range of this category and our previous products was too large. After thinking about it, in the production of mold, I often went to the factory in those months, and finally went on the market at the end of September as I wished. A product that was not very promising at the beginning could produce 10K per month. It continues to this day. I am very grateful! This product boldly tried to place silicone dolls in the transparent water tank to break the user's general understanding of beauty products and increase the fun of using them. This is a perturbed verification process. Fortunately, it was finally recognized. We will also update and replace some limited editions according to the festival, such as Christmas elk, summer fruit, net red flamingo unicorn, etc., constantly input fresh blood, and also follow hello kitty, sailor Moon, Tmall and other cooperation, constantly looking for more possibilities, but also slowly found a way suitable for us.
