Grindenstein Red Knock Box

Grindenstein is a compact knock box that bangs out your coffee grinds.

Designed to be stored on the espresso machine's drip tray (under the group head) reducing clutter on the kitchen bench. A thick and durable rubber sleeve protects the group handle, absorbs the strike force making it quiet to use.

Grindenstein's patented shock absorbing design and solid steel core make it truly impossible to break.

Includes a booklet with great ideas on how to recycle the collected coffee grinds.
