This is an accessory set for those using an espresso machine with a 51mm basket (in my case, a De'Longhi Stilosa and Active). The famous brand item is the MUVNA WDT distribution tool, but the others were obtained from sites like Temu. They may not be much, but for those using a De'Longhi Stilosa or Active, this set significantly improves the quality of your espresso, so you can think of it as an introductory set for本格 espresso. Besides this set, you can start with a 51mm bottomless portafilter (note that there are several types of 51mm). Set contents: 51mm MUVNA WDT distribution tool x1 51mm basket x2 51mm dosing ring for the basket 51mm spring tamper Magnetic wooden box for 51mm paper Thank you for viewing.
