Also known as a “bash bin” or a “coffee column,” a knock box is an essential tool for espresso machines — and the user-friendly EspressoWorks Espresso Grounds Knock Box makes storing espresso grounds easy and convenient until baristas are ready to dispose of them.

Featuring a middle rod to let you “knock”, the box is large enough to store the used grounds of a few cups of coffee.
