Thank you for viewing. This is a listing for a MHW-3BOMBER coffee tamper. It is 51mm in size, mainly for use with home espresso machines such as De'Longhi. This is a constant pressure tamper, which is expected to have the effect of keeping the load on the coffee grounds constant during tamping. The contact surface with the grounds is black (titanium color), giving it a luxurious feel. It was purchased new in March of this year and has only been used a dozen or so times. I think it's in good condition, but please understand that it is a used item. The price includes shipping. Thank you for your consideration.
