This is a large color mixing plate/Palette that is foldable. Because it's semi-airtight, your colors will keep wet for a longer duration of time. This is made out of sturdy plastic that is super white. You will appreciate its high-quality plastic once you see it. The wells are redesigned to be deep enough to hold more water/color. The wells have rounded corners that help it to get cleaned easily. This tray is mountable and recyclable. Note: Once folded and locked the water, if any, can still seep out, we don't claim this product to be water tight.
