Along with your brush, your mixing palette is one of the most important tools for marble nails, whether you're using inks or watercolors. When working with highly pigmented paints like color inks or watercolors, some mixing palettes can become discolored. That's why I like to use mixing palettes that aren't made of plastic. This mixing palette is made of glazed ceramic and can be used with both inks and watercolors without discoloration. Dimensions: 115 mm x 115 mm. However, you should still clean your mixing palette after each use.
