This practical insert is designed to provide an optimal solution for owners of 57mm portafilters, such as those found in Lelit Anna and Lelit Anita espresso machines. It enables precise and stable tamping of the coffee powder by converting a standard 58mm tamping station, e.g. from Mojae, to the specific 57mm size. This ensures that your portafilter sits firmly and securely throughout the tamping process, which is essential for achieving a consistent and tasty espresso. The insert fills a need for accessories for this less common portafilter size, making your coffee preparation easier and more efficient.
