In addition to its innovative design, I love that brush is so clearly inspired by my fave B bed dweller, BERT! What's more fun? Not one thing. I mean, is the resemblance not so very OBV?
Now, Givenchy's Phenomen'Eyes ($27) is expensive, but impressive. The wand takes some getting used to. But trust me, you will get better with practice. The formula is amazing, one coat will give you defined, curled, separated, long lashes. The shape of the mascara allows for more precise application to each individual lash as compared with a regular mascara wand.
The not-so-great news is that it also takes longer to apply Phenomen'Eyes. Also, it's impossible to sweep the brush over the top part of your upper lashes (as in, on TOP of your lashes). I find it's best to sweep a regular mascara on for the tops of lashes, and then further define and lenthen from underneath with Phenomen'Eyes. Have your lash comb at the ready because it can clump, but the definition and length this mascara provides is MAJOR.
Have you tried Phenomen'Eyes? What do you think?
