This product is a newly developed patented product by our company. It has an ashtray on the top, which is more novel. The teeth are pyramid-shaped with serrations, which makes grinding easier and the grinded things are finer. The product has a threadless design and adopts a fast thread design. It has changed the phenomenon that traditional threads are easy to get stuck and slip. At the same time, the filter adopts a detachable design and can be removed directly, which is convenient for customers to replace and clean by themselves. This product has been deeply loved by customers since its launch.
