This is a great paint pan for kids.  It has all the colors that kids like to use.  Just a little bit of water added will have them painting beautiful pictures.  Add a little more water for a water color look.  You can achieve deep colors or washed out colors and your little ones can spend an afternoon being artistic.  It works well on coloring books or plain white paper showing up with bright colors.  We even used them on plain wooden banks, and it worked pretty well with that too. 
The lid can serve as a mixing dish to make their own colors.  It also easily cleans up off tables and little hands.  There is enough paint to last for a good while, so you don't  have to worry about running out quickly.  
Pros:  Keeps you little ones busy being creative and learning about colors
Easily cleans up,
