La Marzocco has introduced the brand new Precision Portafilter kit: a special range of filters and portafilters accurately selected from its superior accessory line. The kit includes two, three or four Precision Portafilters and 17-gram baskets, and is compatible with all La Marzocco machines. Every portafilter has been weighed with a high precision certified scale in order to guarantee that every portafilter in each kit differs from one another by only ±0,05g (±0,18 oz.).
