L'Oreal Infallible Eyeshadows

They are very opaque and most of the line has a metallic shimmer, though there are a few that SEEM to be more matte (could be wrong about that because I haven't tried them yet). They are easy to blend and the staying power is great. I haven't had any trouble with smudging or any creasing, although others HAVE reported that they have had trouble with creasing. I tend to apply my shadows over powder and/or foundation out of habit so it may depend on what you're layering them on top of (bare skin vs foundation, primer, etc).
I had some trouble getting the camera to pick up these shadows to my satisfaction. Each of these have a real depth of color that is just gorgeous. Eternal Sunshine (the gold one) unfortunately doesn't show up very well against my ghostly skin, especially in this photo, but it does look nice, albeit subtle, in person. I attribute that mainly to my paleness. Liquid Diamond (silver) has this intriguing lavender undertone that I adore. They can be blended out to be lighter but I have swatched them at the fullest opacity possible in the photos below, which again, they really don't do justice to. I did not use primer on these swatches because, frankly, they did not need it!

I definitely plan on getting more shades. In fact, while I was taking a break from putting this post together I went out with the husband and bought another while we were out. I wanted to get Perpetual Purple because I'm a sucker for purple but my limited budget convinced me to choose a more versatile shade.
I picked Iced Latte, it's a beautiful shimmery creamy/taupe/gold type color, it's hard to describe! It's a lovely and like I said, very versatile and can be used in many looks.
It does have a higher price point for being drugstore eye shadow single. They sell for around $8 a pot but there is a very generous amount of product and a little goes a LONG way. I can't see running out of them any time soon. To make them a bit more affordable try searching for a coupon and getting them when they're on sale at drugstores. I have seen them go on sale for B1G1 or B1G1-50%off.
So if you're on the fence about these I would definitely suggest giving them a shot, I love them!
