This one I didn't really know what it was when I made it. I had to ask it and the answer was it could be functional. It said it could do a better job of holding and displaying pens and pencils than the cup that held too many inferior pens and pencils. Most of the time the pen was dry, or the eraser was too old and hard, or the pencil was not sharpened. Now life will be more peaceful with a working vase. Working vases maybe my next painting. After all vases that hold flowers also work.
