I love how tiny the pencil is. It allows for great precision when filling in eyebrows. I have one gripe though - I can't seem to find the shade Black anymore. I'm not sure if they discontinued it but I really wish they'd bring it back.
I struggle to find a pencil dark enough for my brows and Black is the perfect shade. It is firm but not hard so you don't need to worry about it smudging. It stays put all day - even if I shower carefully!
It comes off easily too and is just the perfect brow pencil - cheap too!
I LOVE this pencil. I have super blond, basically white brows and it covers them like a dream. Also looks natural due to thinness of pencil tip.
