**EXTRACTION IMPROVEMENT:** Using a bottomless espresso portafilter allows you to observe the extraction process closely, aiding in identifying and rectifying extraction issues—an excellent tool for enhancing your coffee-making skills.
**HIGH QUALITY:** Made from food-grade stainless steel, the portafilter head is carefully cast and polished by hand for precision. The handle, crafted from 100% natural solid wood, features an ergonomic design that promotes a comfortable grip and effortless control.
**PLEASE NOTE:** Our portafilters are engineered for a snug fit in the group head of CASABREWS 5700 series, Neutron Pro, Ultra, and 4700Gense, ensuring a secure seal during brewing. Due to variations in machine tolerances, some may have a tighter fit than others. We recommend checking the position and thickness of your portafilter's ears, which measure 5.9mm.
