Dispose of those pesky grounds easily with this Knock Box Drawer by Lelit. The pull out drawer is where you discard your used coffee pucks. Inside the drawer is a knock-bar where you hit your portafilter against. The side bin connects to the drawer with magnets. It can be relocated from the left to the right or even the back. You can use it to store any loose parts and accessories. This knock box drawer now comes with a cleaning brush and cloth wipe. The wipe has a hole if you want to hang it. The brush has the Lelit logo on the handle.
