Here is a genuine ceramic coffee filter holder to make pour-over coffee everywhere with just a filter, coffee and boiled water. You can put it on a large cup or over a thermos can. It was made in the Netherlands by Royal Raja for Douwe Egberts Coffee aka DE, probably late 1990’s. Signed and in great shape with minimal signs of use or age. You can make ca. 2 cup – a liter of coffee when completely filled with coffee. See the attached Youtube video on how to make pour-over coffee.
