ColourPop Mulan is a limited edition eye palette that retails for $24.00 and contains 0.53 oz.
ColourPop Mulan 15-Pan Shadow Palette ($22.00 for 0.60 oz.) is a new, limited edition palette that launches on March 19th at 10AM PT. The matte eyeshadows were pigmented, blendable, and wore between seven and eight hours with a few shades being a little powdery. The shimmers varied a bit more in performance with some having full coverage and being easy to use while others had a bit of fallout during application and/or wear.
There were a few shades in the palette that seemed to contain glitter (to my eye/by feel), though smaller in particle size, so I read through the ingredient list more thoroughly. That being said, only Be Swift had an asterisk and a warning that it was not intended for the eye area.
I'm not sure what makes polybutylene terephthalate, or PBT, which is also a thermoplastic like PET glitter, more/less safe for eyes other than what I'm seeing: smaller particle size and a smaller percentage of the product is made up of that single ingredient. There was also PET glitter listed (further down in the ingredient list) for Like a Girl, Brave, and Legacy. Based on some of the other mainstream brands (MAC, NARS, Urban Decay, to name a few) that have released eyeshadows using PET glitter (and saying they're to be used on eyes), smaller particle sizes and/or a smaller percentage of PET glitter are often the commonalities.
