Hailing from Berlin, Treat Collection is the only 5-free nail polish worth its salt that I've found so far. The bottles are sleek, the formula isn't clumpy or runny, and the polishes dry hard and actually last. Plus, the colors are sublime. I've often gazed longingly at the Chanel polishes since deciding to clean up my beauty products, but Treat Collection ticks all of my boxes. I picked up Sugar Frosting and So Simple and while you can't tell in the picture, both have a very subtle gold shimmer laced throughout. Metallic polishes always last a good deal longer, and I gravitate towards polishes with some glitter or shimmer to help anchor the formula.
