No more mess! Why dig out the spent espresso coffee puck with a spoon when it is much easier (and cleaner) to knock the coffee out with a knock box. This sleek stainless steel accessory helps you knock out the most tightly packed coffee pucks for easy, mess-free cleaning. It is slightly weighted and features an anti-slip bottom grip for increased stability on the countertop. Plus, it is completely dishwasher-safe for convenient cleaning.
