Thick and durable rubber sleeve protects the group handle, absorbs the striking force and makes it quiet to use. Grindenstein’s patented shock-absorbing design and solid steel core make it truly impossible to break. Specifically designed to be stored on the espresso machine’s drip tray (under the group head), Grindenstein’s unique height reduces clutter on the kitchen bench top and fits easily in the top rack of the dishwasher.
