The Twinkle Twinkle palettes by the brand Profusion Cosmetics are four eight pan palettes of shimmery eyeshadows. You can find these palettes on eBay or Amazon, as the brand's site does not appear to carry them.
I picked up the first three of these palettes that I owned several months ago, and only recently was able to find the fourth palette. I found them at my local Dollar Tree, for only a dollar each. Since they are not available on the Profusion website, to obtain these palettes, you have to search for them online, so prices for these palettes can vary. I've seen everything from one cent to more than five dollars, but even then they're extremely affordable, if you can find them.
As for the packaging, the shadows come in a long plastic compact. The clear plastic lid has the product name, and company logo printed in a metallic silver. The lid can be difficult to open at first, and chipped my nail polish a few times from wrestling with it.
The back of the palette has a full ingredient list, also printed in silver.
Inside, the eight pans of eyeshadow are laid out in a single row, with a small mirror below them. The mirror is practically useless because of it's position and size.
My biggest gripe about the packaging is that the pans come unglued from the plastic base far, far too easily. I've had to glue them back into two of my four palettes.
Also, the palettes are numbered, but nowhere on the packaging does it say the number.
The texture of these shadows are lovely, creamy, smooth and soft. I've had minimal problems with excess powder getting kicked up in the pans. There is a bit of fallout during use, but nothing extreme, or more than I come to expect from shimmer eyeshadows. They blend easily, and I find them overall easy to work with.
Color payoff is an area where I feel like these shadows excel. Every color, from the bright yellow, to the rich purple, and even the soft beige are all very pigmented. In swatching they never need more than one good swipe to show true to color, even without a primer. I should also note that across all four palettes, there are similar colors, but no exact repeats.
The wear time is really good as well, by my standards. I have worn a look using only one of these palettes, without a primer or a base, for more than seven hours. With a primer, I have had them last for more than eight hours, through a hard rock concert, that I was right in the crowd for, and that was about half of those eight hours. So clearly, they wear extremely well.
So overall, I adore these palettes. Despite being misleadingly cheap, they are possibly some of my best makeup purchases.
I do think the packaging is just plain crappy, and I wish they were easier to find, but I still do highly recommend these palettes if you can get your hands on them.
