At the end of each coffee preparation, the portafilter is cleaned. This is what the knock box is used for, among other things, which is used to knock off the portafilter and thus collect the coffee pucks that are no longer needed. Due to its size, it takes up a lot of space where the coffee is prepared. rb.crafts takes advantage of this and gives the box a new look through wood finishing with a subtle but exclusive character. The box fits elegantly into any concept and radiates warmth and quality. At the same time, the tapping rod, with its thick but soft rubber and stable aluminum core, dampens the sound that is produced when the portafilter is tapped.
