Seeing the new Sephora eyeshadow custom palettes, I wondered if the inserts could be removed to make a freedom palette. They aren't cheap on their own but if you are shopping for eyeshadows anyway, you can get them free with purchase with the purchase of a few eyeshadows. I used the $20 off $50 Sephora discount to get a better deal.
With the insert removed you could easily fit 4 sephora eyeshadows in this palette. Easiest part is that it's already magnetized! Blue shadow is a sephora sized pan.
