I purchased these specifically for the pink in poppy polish. Although I like each color, several are on the thinner side...thinner than usual. I typically want to add no more than 2 coats of polish to make it opaque on the nail. I am willing to make an exception, depending on the polish. A couple of these may be 3 coaters, depending on your nail line and how thick your coats are. I probably will open them up and let them sit for 24 hours to let them thicken up some. The shimmery baby blue one is probably meant to be a topper. It will look better over a similar color or black. If it had only been one set for sale, it wouldn’t have been worth it to me. I got two sets. It’s a nice set, though. Before buying, I suggest you look this collection (or any other polish for that matter) up on YouTube to see how they swatch and look on nails. Just type in the name of the collection. There’s several videos on them. You can also look them up online to find pics of them on nails.
