Good guess!

I ordered this tamper, although no information from the manufacturer / seller were made to the masses. After all, a customer had already written in his review that the larger stamp was 55 mm in diameter - clearly too big for my Pavoni Euro Piccola. But after the old plastic tamper Pavoni of this is to break apart, I have dared to attempt and set to the smaller of the two stamps: Fits better than the original! So that other buyers do not need to guess, here the diameter of the second punch: 48 mm.
