Great question! The cup has embedded magnets built into the base that grip your 58mm portafilter basket securely. When you place the cup on top and flip the whole assembly, the magnetic hold keeps everything locked together so grounds transfer cleanly without any spills. It is a simple but game-changing upgrade for anyone who single-doses their espresso.

This cup is designed for 58mm portafilter baskets, which is one of the most common sizes used by brands like Breville, Lelit, and many E61 group machines. Before ordering, measure the inner diameter of your portafilter basket to confirm it is 58mm (approx. 2.28 inches). If your machine uses a 54mm or 51mm basket, this particular cup will not be the right fit.

Absolutely. The cup is made from food-grade stainless steel that resists corrosion and stands up to daily use without warping or degrading. The interior features a non-stick coating that prevents coffee oils and fine grounds from clinging, so you get a clean transfer every time and the cup stays hygienic with minimal effort over the long run.

Yes, that is one of the best ways to use it! Place the cup under your grinder chute and grind your single dose directly into it. Once grinding is complete, set the cup on your portafilter, flip, and the grounds drop right into the basket. This method minimizes grounds retention and keeps your countertop spotless, which makes it perfect for a fast morning workflow.

Keeping it clean is effortless. After each use, simply wipe the interior with a damp cloth or give it a quick rinse under warm water. The non-stick surface means grounds and oils release easily without scrubbing. Avoid abrasive pads or harsh chemical cleaners to preserve the coating. Dry it thoroughly before storing, and it will stay in great shape for years of daily use.

Absolutely. Every espresso machine, grinder, and accessory is packed with the same precision we put into designing them. We use reinforced boxes and protective cushioning specifically tested for coffee equipment—because a damaged tamper or chipped machine housing isn't acceptable.

In the rare event your portafilter, grinder, or machine arrives damaged, our support team will sort it immediately with a replacement or full refund. No runaround.
