The salesgirl warned me that these dry really quickly, and she wasn't kidding! The work great on their own, but really don't blend with other products. I have tried them with a variety of different brands and formulas, and the shadow really just sits on top of it. I like them for a quick wash of color, and they really do stay put - no need to check for creasing! I found I have to be very precise - my mistakes are difficult to remove. I usually use just my finger to apply cream shadows, but I have to use a brush and be more careful with this product. I like having the one shade, but I won't buy more of these.
