This new ergonomic 58mm portafilter is built in Italy and is made entirely of stainless steel, including the spouts. This portafilter is deep enough to hold any size VST basket, including the 22 gram.
It needs to be addressed that this portafilter does not come with an insert basket. An insert basket will be needed to be purchased separately. There are a variety of insert baskets that can be ordered for this portafilter. This portafilter works on all machines with an E61 group (58mm), and the Quick Mill Silvano.
