Thank you for viewing. This is a listing for the MHW-3BOMBER Coffee Dosing Ring 51mm (Dosing Ring). Purchased in February of this year for 2200 yen. I used it to prevent coffee grounds from scattering when inserting the portafilter into the grinder. There are some minor scratches, but it is still in good condition and can be used. Would anyone interested like to have it? The price includes shipping. Thank you for your consideration. ※ The following is extracted from the product description: ・Premium Material: The coffee dosing ring is made of high-quality 304 stainless steel, which is rust-proof, corrosion-resistant, and food-grade, safe for your family's health. ・The flared mouth of the coffee dosing funnel effectively prevents coffee grounds from scattering on the table during grinding. The coffee dosing ring is a very convenient espresso accessory that prevents wasting coffee and making a mess on your workbench. ・Fits 51mm diameter portafilters: The coffee dosing funnel fits most 51mm diameter portafilters on the market.
