Tossed the palette in my kit all week and the corners picked up a bit of scuffing, which is fine for cardboard. Magnets are strong enough that nothing rattled when traveling. I DM’d a quick question about fit on baked pans and got a short, helpful reply. I didn’t need to use returns. The window makes it fast to grab the right shade, which saves me time on set. Not cheap, but the layout flexibility pays off.
