This past spring and summer I became obsessed with NYX's neat little eyeshadow pencils. The shadows come in chubby pencil form in a rainbow of colors, and are perfect for use as a base under powder eyeshadows or even by themselves. I tend to use mine under powder eyeshadows to make the look really *pop* and last longer, though I do notice creasing after a few hours of wear. I've heard you can remedy this by using another base (like Urban Decay Primer Potion) underneath the eyeshadow pencil, then applying your shadow as usual. But for the price ($4 on NYX's website, though you can probably get them a little cheaper at your local beauty supply store) and amount of product you get, NYX's eyeshadow pencils aren't anything to scoff at.
I love experimenting with different looks and colors with these. For instance, remember that "secret color" shadow I used in my one year anniversary look? Well, that shadow has a tendency to lighten and add sparkle and a dash of pink iridescence to whatever shade you apply it over. It's especially striking applied over a pink or purple base:
There's an infinite number of shadow and base combos to have fun with; NYX's Jumbo Eyeshadow Pencils make it a little easier (and cost-efficient!) to get those lids poppin'
*FYI: I purchased these pencils and all other items up for swatching and review with my own money. I have received no compensation for this post.
