MHW-3BOMBER Square Knock Box 1.2 l – knock out your coffee puck quietly and cleanly
A short, dull knock, and the coffee puck drops into the box. The silicone-covered knock bar absorbs the impact instead of clattering loudly. The Square Knock Box from MHW-3BOMBER in Black holds 1.2 litres and, with its square shape, sits compactly next to your espresso machine.
The container is made of durable ABS plastic. The knock bar is covered in silicone, which dampens noise and impact and protects your portafilter. The bevelled rim keeps splashes inside the box, and the non-slip base keeps it in place while you knock out.
Emptying and cleaning
The knock bar can be removed, so you can empty the box in one go. Then rinse it briefly or wipe it out with a damp cloth and let it air-dry.
How much does it hold?
With 1.2 litres, the box is made for everyday use at home without taking up much counter space. How many pucks fit depends on your dose and how wet the pucks are. In our experience, it is best to empty a knock box daily; that keeps it clean and the grounds are easy to dispose of, for example in the compost.

Who it’s made for
For everyone with an espresso machine who no longer wants to knock out their pucks over the bin. For small kitchens with little space next to the machine. And for anyone who likes to work quietly early in the morning while the rest of the house is still asleep.
Tip from our café: In our experience, the puck comes out most cleanly when you knock out the portafilter right after the shot, with one short, firm knock on the bar rather than several hesitant ones. For the next espresso we like Cozy Nut, our Italian-style espresso blend, nutty and chocolatey. Very Nutty, a strong robusta from India, brings lots of body and hardly any acidity, and Chestnut Delight is the blend with depth and warmth. You’ll find all our coffees under Coffee beans. That’s our recommendation, one of many.
What goes with it
You’ll find more models under Knock boxes and knock-out containers and Knock boxes and drawers, and more from the brand under MHW-3BOMBER.
To protect your counter while tamping: MHW-3BOMBER tamping mat. And for the next shot: freshly roasted coffee beans from our roastery.
