Lines are drawn on the water container to teach children how much water to put in it m(_ _)m (They can be removed with something like "Geki-Ochi Kun") I'll include some used paints (I'm not sure how much is left, but please take them!) and some new paints (^ ^) There's some wear and tear in places, but I haven't used them much, and I've taken good care of them, so I think they're clean (^^) Please feel free to contact me if you have any questions!
