Thank you for viewing. This is a listing for the MHW-3BOMER Espresso Distributor T5201L4. It can be used with 51mm portafilters, mainly for home use, such as those from De'Longhi. I purchased it new in March of this year, but I am selling it due to the sale of my espresso machine. It is in good condition as it has been used infrequently, but please understand that it is a used item. The price includes shipping. Thank you for your consideration.
