I will say they are richly pigmented, that was a plus for me.
They can be a little messy though by getting all over your fingers once they are dipped in water, but that's the creative part of making art, right?
First, I applied acrylic paint on paper, then after allowing the paint to dry, I layered with the crayons. I drew right on top of the acrylic paint. No problems there, moved with ease and you can smooth out lines if you like. They do have a texture similar to regular crayola crayons, but not as waxy.
I liked the crayon look that it gives the painting, a graphic style that tends to be more edgy. You can paint with them by adding water and using a brush, however, I wasn't too crazy using them that way. Perhaps, if you are a watercolor painter, you could appreciate them in that manner. But my favorite way of using the crayons was simply drawing with them. You can add water and blend out your lines. Still my favorite approach was drawing onto the acrylics with free flowing lines and/or circles. I would recommend having a small set of water soluble crayons to add a different element to your art. I would use them again, maybe not often, but worth having on hand. Also, these work great for kids.
I thought these little paintings came out pretty cool.
Take a look at these and tell me what do you think?
