This is how I store my pigments. It was really hard for me to find craft containers with separated compartments that fit my pigments, so one day I decided to store them temporarily in a shoebox lid. I never ended up moving them and it got full, but at least it works! And luckily it fit the pigments in snuggly so they don't roll around. I don't plan to move my pigments around or else it'd get messy. They sit nicely in my drawer and I pull them out when I need them :)
