I am such a fan of the Benefit products so this one I just had to have.
It is so useful for women who have very full eyebrows and dont need to colour in the whole brow in order to get the brow-pow that you are looking for. It is perfecting for filling in small patches or just lining the edges ( It has a very small end that is as small as a pall pointe pen ). Its size and colour are super convenient. The is a doubled ended tool, one side has the actual colour pen and the other end has an eyebrow brush that also helps shape the brow.
