This is most likely a replica of a Qing dynasty ink set (“仿古墨”), made as a gift item in the 1970s or 80s using old designs. The ink looks like it could be okay quality pine soot, although the paintwork is sloppy (one feature that tells these apart from genuine Qing ink). Nonetheless these are a fun way to snazz up your studio, not to mention full of cultural and economic history.
