In original box - Mr. Coffee paper coffee filters - great for display. Mr. Coffee started selling coffee filters in 1975.
If this is not the first design used, it is certainly among the first designs.
Good used condition: box has been opened and a few of the paper filters are missing; some wear / stain on box, see photos.
