Melitta 1×4 filter holder with glass coffee pot in box 1980 Germany

Here is a never used 1×4 filter + glass coffee pot made by Melitta from Germany in the 1980’s. It is a system that requires a paper filter (not included) to hold the coffee grind and used with hot water pouring over. There are only small  signs of age on the package, no signs of use. The original package measures ca. 30 cm or 12 inches high. Check out the attached video on how to make coffee vintage style!
