✳︎As shown in the last image, there are slight scratches on the coaster. This coffee dripper can be used repeatedly without paper filters. The far-infrared effect and micro-holes remove chlorine odor and impurities from the water, allowing you to enjoy smooth and easy-to-drink coffee. It can also be used as a water purifier. The underside of the coaster has grooves to stabilize the mug and filter, preventing them from slipping.
