I found a one in a charity shop recently. Hinged, rectangular, with a viewing window in the lid. All the christmassy colours.
Perfect for storing paints if you’re a watercolourist. We put teeny magnets under the little paint pans (which you then squeeze tube paint into). I love swapping my paints between colourful tins, depending on the times of year or the theme of my painting.
Some artists put white enamel paint across the inside lid of the tin, to make it into a mixing area. It’s crazy how much some vintage tins go for on eBay.
