Do you actually open the bottle of nail polish you are about to purchase to check on the brush? Because I don't and I learned that there's a good deal in doing so, the hard way.
I purchased The Face Shop's polish in BR806 and I was horrified to see that my new bottle of polish had a brush specially designed for Hulk's nails. Sigh.
I'm reluctant to return it (even if it's unused) because I'm doubting The Face Shop will replace it. I know I have to try but it's not worth my time if I can't get it replaced since I purchased this from a branch faaaaaar from where I live.
