The Tubbi knockbox is the perfect accessory for home baristas to help you dispose of your espresso pucks. It has been over a year in development and gone through many prototypes but finally we got there in the end with a brilliant, yet very simple design. All it is, is a plastic tub and a bar! No nuts or bolts or anything.

The knockbox may be small but it can comfortably hold 10 double pucks of coffee before it needs emptying. To empty just lift the rubber bar out and discard the coffee as you wish. A silicon ring on the bottom prevents it moving about the place and also helps to reduce the noise.
