I think it's a great idea, but the price is putting me off. It'd cost £84 for me to fill a palette, assuming I kept Walk of Shame. I do like the idea of being able to have 6 colours I've chosen, and will use regularly, though, rather than carrying around a palette with surplus shadows in. It'd also be refillable, and I'd be able to swap colours in and out, which are points in its favour as far as I'm concerned. I can't really justify spending that much money on it, though. Their pre-filled palettes are much better value, even if they're not perfectly tailored, so I'm pretty sure I'll be sticking to those. Unless I win the lottery, or something. Then you never know!
