Adult Coloring Recommendation

I have been coloring for a few years now and this is one of my favorite things I've come across. It's called Color Escapes, put out by Crayola. It includes 12 sheets of coloring pages, 12 pack of markers and 50 pack of coloring pencils (not pictured). The one I have is called Geometric. There are three other ones called Garden, Nature & Kaleidoscopes. 

Color Escapes: Geometric
Color Escapes: Garden
Color Escapes: Nature
Color Escapes: Kaleidoscopes


These kits are sold at Crayola & Amazon.
