These palettes are great for their intended use. However, I use these constantly next to my work area for multiple uses - gluing, keeping track of die cut pieces, holding sequins and pearls, anything messy as they are easy to clean, etc. I love the fact they are white. I place them on top of my black glass working surface when measuring with clear, plastic rulers. I think a white surface is so much easier for many things than the black. The only problem I have had is that 3 of the 4 large ones I have arrived quite warped, but a heavy object has helped to flatten them.
