Knock! Knock! Who's there? It is no joke…Knock boxes are handy to have and easy to use. Turn your portafilter upside down and give it a good smack against the inner bar or side of the box to loosen the spent espresso puck. Keep the mess in the box, and the flavor in the cup. We stock many knock box designs and sizes to choose from the most utilitarian plastic container to hand crafted maple masterpieces.
