I like myself a good shimmery eyeshadow and I have quite a few but one of the most intensely sparkly shadows I've ever come across is this Jewel Pot for the Korean brand, Peripera in the shade Be Lovely.
This thing is insane. I tried my best to capture its brilliance but unfortunately the pictures don't do it any kind of justice.
This is one of the very few eyeshadows in my collection that I have to be careful with how much I apply. Too much and I will readily admit I end up looking a little crazy...
If you are a fan of a little (or a lot) of sparkle in your day, I would check these out. Pretty much any site that sells Korean beauty products should stock them.
