Grindenstein Knock Box
The Grindenstein is built for shock absorption with a solid steel core, making it truly impossible to break. The extra durable rubber sleeve absorbs shock, thereby protecting your group handle and making it quiet to use.
It's designed to be stored on the espresso machine's drip tray (under the group head). Perfect for reducing clutter in the kitchen. Easily fits most dishwasher top racks as well.
