・ Orders are generally shipped on the same day if payment is received by 12:00 PM, but there may be unforeseen circumstances such as illness that prevent same-day shipping.

This is a 21cm long tube brush that can clean tubes with diameters ranging from 2mm to 24mm. For DIY maintenance of De'Longhi Magnifica, this is necessary for cleaning the outlet nozzles when the flow from one side is poor, and for cleaning the inside of the generator's discharge rod. If one side of the De'Longhi Magnifica's outlet nozzle is narrowed due to dirt, it can be quite inconvenient when brewing two cups, as one cup may fill more than the other. You might try scrubbing with cotton swabs, but the sizes can vary, being too small or too large. With a variety of sizes available, you can use this brush for various tube sizes, so it's wise to have a set on hand.
