Modern Stainless Steel Knock Box with 8.5" X 4.75" Tamper Base
This modern knock box will take care of all your messy coffee grounds, and keep your counters nice and clean. The non-slip rubber base also has a built-in tamper holder & tamping station.
The knockbox itself is made of 18/10 stainless steel and measures 4-1/2"W x 4-3/4"D x 6-1/4"H. The tamper holder will hold any tamper up to 58 millimeter, and it can be used as a tamping station: put the portafilter base into the hole, and tamp. This protects your counter!
