"The first that comes to mind was by Olive & June, a nail polish company based out of California. I noticed an ad of theirs appear in an Instagram story and remembered thinking the name was unique, but I didn't think much more about it. A couple of days later, they appeared on my Instagram feed. At first, I thought it was a post from a friend. The ad was so simple and seamless that it didn't feel like an intrusive ad at all, and the colors and quality of imaging made me finally check out their page. I was impressed by how fresh and fun their content looked for a nail polish company, and I realized that their products were more than just nail polish. Within an hour, I had gone to their website and purchased a full kit. I'm still a huge fan!"
