This is a single Dosing Ring 51mm Black. We also have silver and sizes 53mm and 58mm in stock, so please inquire. The third image shows 51mm/53mm/58mm from the right. This is a dosing ring (funnel) for espresso. It is placed on top of the portafilter to make it easier to catch the powder coming from the grinder, effectively preventing coffee powder from scattering. Magnets are embedded in the ring, which adheres to the metal filter and does not easily fall off. This 51mm bottom diameter is for espresso machines with a 51mm filter diameter, such as De'Longhi, but please confirm compatibility before purchasing. The item is new and unused, but please refrain from purchasing if you are sensitive to minor imperfections or if you are looking for an unopened, brand-new product. 【Specifications】 Material: Aluminum, Magnet 51Φ Size/Weight: Outer diameter: 62mm / Ring outer diameter: 51mm / Overall height: 22mm / Weight: 34g (Reference) 53Φ Size/Weight: Outer diameter: 64mm / Ring outer diameter: 53mm / Overall height: 22mm / Weight: 37g 58Φ Size/Weight: Outer diameter: 70mm / Ring outer diameter: 58mm / Overall height: 22mm / Weight: 41g Shipping costs will be discounted only when combined with other items.
