Holbein Enamelled Metal Folding Palette #500 Rare

Holbein Metal Palette #500, rare, I believe this palette has been discontinued. Please see pictures for condition of item, condition seems good. Some slight rusting, a lot of thin small scruff scratches outside on the black paint, some paint chipping here and there, some paint stains inside, etc. I’m not sure what kind of watercolor brand paint is inside, most likely Holbein watercolor paints. flawless for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
