Grindenstein Coffee Knock Box


The Grindenstein knock box makes it easy to bang out your espresso coffee grinds.  The coffee grind bin comes in 3 colours, is super solid and sturdy, dishwasher safe and even tucks away on the drip tray of your espresso machine for space-saving storage.  The thick rubber sleeve absorbs the striking force protecting your group handle. 

Each Grindenstein also comes with an information booklet on the best way to use coffee grinds as a natural fertilizer in the garden.
