In the Barista espresso knock box by Cilio, you can easily knock the funnel or the portafilter of your espresso machine firmly against the bar and empty it into the container. The coffee grounds are also a good plant fertilizer and serve another purpose in the garden. When placed as a small barrier in a flower bed, it prevents ant trails by neutralizing the scent trails of the insects. The silicone-coated knock bar is removable and features non-slip feet. Dimensions: 16 x 16 cm, height: 11.8 cm. Material: stainless steel, powder-coated.
