I have 3 mini makeup brushes and I'm gonna show them to you.
I have only 3 brushes but I love them so much as they are so small and easy to carry anywhere I go.
You can insert these brushes in to any bag you carry and because of the small size ,even you can put it in a wallet or a purse...
2 lip brushes
2 eyeshadow applying brushes
and some more (not in the picture)
This is the review of my small brushes and most importantly they are not long than a nail polish bottle
( IT IS a little longer than a nail polish bottle, but not much .. lol)
