I've been looking at this for months. I mix foundations on the side of my hand, so this seemed like a great solution. I think it will be, if you have a lot of room and a lot of makeup. It's about 6 inches in diameter and 1 inch tall. I looked at all the pictures and descriptions I could find and I thought it would be at mos three inches across, so it might fit in my makeup bag. There is no way I could mix up foundation and take this on a trip, if you've already got big palettes and lots of space for makeup, you might love this. If you're consolidating, like I am, this might be a great idea but too big.
