Day 1 - L'oreal on eye on right in the unlabeled pics, Exceptionnel de Chanel using Explosion brush on eye on left in unlabeled pics.
Conclusion: Yuck. I think the reason I like the Chanel is because of the brush it comes with. Using the Explosion brush didn't really do it justice. It's better than the Explosion but not good. I think tomorrow I may try the brush w/ Prestige My Biggest Lashes.
