Well for the etude house round ones. They can pop out of the plastic casings and be put into a separate case. Customize-able eye shadow palates are a plus. Even though 7 dollars is a bit pricey for one small eye shadow the brand is good quality. Etude house and tonymoly (tonymoly also has epic lip stuff too)
Thanks so much for explaining for me @xShortAndProudx. $7 is a bit pricey, but if it's good quality, it's worth it and an eye shadow palette is definitely always a necessity. So I def love the fact that they can pop out of the casing. I've checked out a few of Tony Moly's products, really nice.
