I love the Ardell brand for false lashes. The demi and demi whispies are my personal favorites. The price is great and the quality is consistent. You can also purchase them just about anywhere, unlike some more expensive brands.
I love the double-ended brushes. I, personally, use the smaller tip to clean up any rough edges from my liquid eyeliner on my top lid or right under my lower lash line if it looks like some mascara may've hit. It's a great and versatile brush!
Eyelashes are one of my "guilty pleasures" but, to me, these are too expensive for what they are. I'll stick to the cheaper brand I can get at just about any store. These aren't a "bad" product, but nothing special that you can't get in another brand.
