This coffee bean grinder is based on the original hand, equipped with a micro motor, so that it can be a key grinding beans. The filling and filling parts of coffee beans are made of frosted translucent silicon boron glass material, which makes the whole coffee grinding process visible and increases the ornamental value. And the grinding scale is set at the rotating shaft, which is convenient to adjust the grinding thickness. In the investigation, we also found that many coffee lovers can't control the quantity of coffee beans, so we set up a weighing scale display at the bottom of the grinder to make the amount of coffee beans accurate every time. Life should have a sense of ritual.
