No need to empty the paint cups after every art session. Just insert the brushes in the non-spill cups, and it seals the lid until next time.
The cone on the paintbrushes shield little fingers from splatters and prevent over-insertion into the paint cups. And the base is flat, so brushes can stand up on the table (instead of rolling off and making a mess).
Lazy Susan caddy measures 9" in diameter x 3¼"H, non-spill paints cups measure 3" in diameter x 3"H, and paintbrushes measure 4¾"H x 1½" in diameter
