I love these paints! They are perfect for travel art making. They screw together for a compact and many color choice little batch of amazingness. I hadn't really worked with pan watercolors but I love these. They're reasonably priced and excellent... Do they have refills for these? Because I feel like I am going to run out of a few colors. :( Already. I tend to use watercolors ata less watery consistency, so maybe that's why they go so quickly for me.
