Stainless steel coffee dripper Economical as it allows you to brew coffee without using paper filters! And it tastes even better than when using paper filters! (This is my personal opinion) Since the tip is immersed in the extraction liquid, it's also useful for extracting beverages like green tea, which are steeped for a while. Please note that the mug in the photo is not included. The coffee beans should be ground medium to medium-coarse, and it's suitable for dark roasts. Due to shipping costs, the item will be sent in simple packaging. Please consider this before purchasing! From the product description site: 【Professional Coffee Filter】This is the same coffee filter used in professional coffee machines. The inner layer is made of high-density, ultra-fine metal wires. The outer layer is processed with thick stainless steel material. The two-layer stainless steel structure extracts coffee oil, making the taste smoother and richer. 【No Paper Filters Needed】You don't have to worry about the smell of paper filters, and it brings out the flavor of the coffee.
