Presenthem espresso knock box is made of pure natural solid walnut wood, which has a higher density than mahogany, is resistant to knocking, less prone to deformation and cracking, and more heat resistant. Hard tapping on the box is not afraid of damage. 8 rubber anti-skid pads are placed at the bottom of the base, which can effectively prevent the sliding of the knock box and the wear and tear of the tabletop. It is more stable and labor-saving when you press powder.
