I'm using the four-color case from before the refurbishment, but I decided to get this one as well. I think the smoke black is stylish. The size is not much different. Since swapping them out isn't that much of a hassle, I plan to use this one, which lets you see the color from the outside, and the one from before the refurbishment with the mirror.
This case holds four Addiction single-color eyeshadows. You set the eyeshadows by peeling off the sticker on the back, but once they're in place, they can't be removed. The case has a little bit of room, so they shifted slightly, but it's impossible to fix. If they were removable and interchangeable, like a custom palette, I'd give it 6 or 7 stars.
It got so scratched that it fell apart, so I bought a new one. Is there any way to prevent it from getting scratched?
It's nice that it's clear and you can see the contents inside. Other than that, I think it's neither good nor bad.
I had some favorite 4-color single eyeshadows, so I put them all together. I also managed to fit eyeshadows from 6 or 7 years ago when they had cheap packaging, so I think I can store all of my pre- and post-renewal eyeshadows together. There's a small gap in the middle, but it's not that noticeable. I reattached the sticker on the back of the single eyeshadow myself, but I wouldn't recommend it for people who want perfect results lol.
