Initially bought this because the eye brow comb/brush was out of stock and I needed something to groom my brows.
Turns out it works even better than the brow comb duo (which I bought later on) as its much easier to use and quick. The plus is that I can use it for my eye lashes too and it works great in separating lashes!
I suppose its quite similar to the ones other brands carry, but I like my shu one and the size is quite handy, not too long, not too short. Another thing is I washed it quite a lot and its been holding up nicely. This is a definite staple for me =]
In terms of price I think it was around 30ishHKD not too sure as I bought it a while ago, but it wasn't expensive quite affordable.
perfect to apply mascara on corner lashes. Gets every little one. I think it was also $5 at Sephora.
