This is a single Dosing Ring 58mm Black. We also have silver, 51mm, and 53mm in stock, so please inquire. The third image shows 51mm/53mm/58mm from the front 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 58mm bottom diameter is for espresso machines with a 58mm filter diameter, such as the standard E61 group head for commercial use, 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 are looking for a completely unopened, new product. 【Specifications】 Material: Aluminum, Magnet 58Φ Size/Weight: Outer diameter: 70mm / Ring outer diameter: 58mm / Overall height: 22mm / Weight: 41g (Reference) 51Φ Size/Weight: Outer diameter: 62mm / Ring outer diameter: 51mm / Overall height: 22mm / Weight: 34g 53Φ Size/Weight: Outer diameter: 64mm / Ring outer diameter: 53mm / Overall height: 22mm / Weight: 37g Shipping costs will be discounted only when combined with other items.
