DESIGN: The cleaning bristles are arranged in an arc crosswise and horizontally to effectively remove the residual powder in the powder basket. For cafe baristas, it saves time to wash the portafilter with water each time, making the operation more efficient. MATERIAL: The handle of the brush is made of beech wood, which is full of color, solid and durable. APPLICABILITY: The cleaning brush is designed for the 58mm portafilter basket. Because of the curved bottom design, the 53/54mm portafilter also can be cleaned, but not as well as the 58mm basket. TIPS: Because the hair planting process requires high-frequency punching, cracks will occur at the bottom of the wooden handle, which is unavoidable, but does not affect the use and appearance of the surface, please be aware.
