19th Century Inkwells
This item is very old and outdated. Even our grandparents might not know what function it serves. It looks like something that belongs in a museum or is sold at an antique shop. It’s a double inkwell that was used in the 19th century.
Considering none of us grew up in the 19th century, it makes sense why this object remained a mystery. The well is used to wash your pen after using it to write so the ink doesn’t clog the tip. You could also use this for two different colors of ink by putting one color in each of the wells (via Everyday Monkey).
