Maybelline Lash Discovery — $7.00
This micro brush claims to be able to catch every lash. Makeup artists say they love using it on lashes that already have length (lucky!) but need a little oomph. Amazon customers love it for its lightweight spoolie and formula, saying it gives easy length and volume without clumping—many have even begged Maybelline to never, ever change their formula or discontinue this line.
