I'm having an issue with the Ruby Wing polish (owned by Color Club). I didn't get this in a Birchbox, but recently purchased a couple of bottles - Peony and Poppy. I love the colors and the color-changing in the sun is awesome. The floral fragrance is also nice.
However, the Peony color has these random, tiny granules floating in the bottle. Before every nail is polished, I have to inspect the paint on the brush so I can scrape the specks off first. I am not finding this in the Poppy color, so maybe it was just a manufacturing issue with this particular batch of the Peony shade.
