Wega VBM stainless steel shutter for espresso coffee machines. It is 58mm. It does not darken with use and does not lose its enamel. Thus, the coffee does not absorb negative odors from the wear of the shutter and does not leave a bitter aftertaste due to the shutter. With the straight "ears", it is for the models: Atlas, Polaris and for the VBM Replica & Lollo models. Does not include a cup filter.
