I purchased it by confirming that it is almost the same as the size of the brush I was using originally, but the brush part was small and the hair was small. From next time I plan to purchase something bigger.
It is smaller than ordinary blue guy. Since the amount of hair is unexpectedly small, I do not know unless you use it. In fact I wanted to evaluate 3, but because there are few reviews, so avoid being criticized and being sweet 4.
