If you’ve got a big watercolor collection (or you’re constantly mixing half pans, full pans, minis, and random specialty sets), this video is all about a simple storage solution that actually keeps things usable: the Paul Rubens plastic palette box. I walk through how I combine multiple Paul Rubens half-pan sets from their little metal tins into one larger, latching case so I can see everything at once and build a custom layout that fits how I paint. What I love about this box is the flexibility. It’s roomy enough for a huge amount of paint (think: up to 128 half pans, or 70+ full pans per side), and it also leaves space for extras like gansai, tubes, brushes, or pens—so it can function like a portable “all-in-one” kit. I also share where to find the blue and pink versions, plus options for neon/opera-style paints if you’re interested in black-light effect colors. If you’ve been frustrated by mismatched pan sizes and too many tiny tins, this is a practical way to consolidate and actually use the paints you already own.
