Resin ABS is non-toxic, tasteless, in line with pharmaceutical, food and other industry health and safety requirements: good oil resistance, smooth surface, easy to clean. The filter handle uses a double-layer structure of filter mesh with professional Italian coffee maker, which has good filtration effect. The inner layer of filter paper is woven with ultra-fine metal wire with high density, which is insulated from the coffee powder. The outer layer of thick stainless steel sheet is laser perforated, providing an extra layer of protection. Foldable design: you can take it with you.
