This is a fabulous unit. I love to slip it in my purse and I am ready to paint without having to juggle anything- it all snaps into place. Great for journaling and taking for spur of the moment painting. I really love this set. It is exactly what I wanted- an ingenious design. I only wish that they would have thought to provide sources for the cartridges at the time that they sold the units. I would like to be able to put certain colors in cartridges that I do not use as often in case I want to exchange them.
