The fun part is personalizing your art kit. You can use an empty Altoid tin or any container. The clear plastic container in the demo held silicone ear plugs. I like the plastic because it doesn’t rust.
Have fun experimenting with different ways of attaching the watercolor kits to your arm. I’ve tried velcro, elastic and snaps. Velcro is the easiest to put on by yourself.
Watercolor tubes (how ever many colors you want to use)
Velcro (it needs to be able to wrap all the way around your wrist)
Altoid Tin (or any container that catches your eye)
