This is a genuine Rancilio tamper. I accidentally bought two, so I'm not using this one. It didn't come with a box or anything when I bought it. The photos show it opened, but the item for sale is unopened and still in its bag. It fits 58mm diameter filters, such as those found on the Silvia, Silvia Pro X, and Epoca S1. Please refer to the internet for more details. This item has been in someone's possession, so please understand that before purchasing. I cannot create a dedicated listing or hold items.
