First of all Sakura is a good brand. My Granddaughter told me about these. They use these in her art class. She tried these Sakura Color Oil Pastel Set. She said" these are the same. I have tried these  to see how well they blend. Water no, because these are Oil pastels. With something like Turpenoid yes these blend well. There are good video on how to use them. Please, do not throw art supplies away, schools can use them. These are not only for adult use, children can use them to. I think they should keep them out of the mouth. Read directions before allowing small children to use them. Folks at nursing homes could use them. Have a good time playing with these.
