The Hakuhodo J series is amazing. They are so soft ans luxe. I use this brush for highlighter and blending out the edges of my blush with powder. This brush is such high quality. I missed out on the Mac 165 and have been waiting forever for a repromote, but then I found this brush that seems similar in size. So glad I got this Hakuhodo brush instead. Don't waste your money on Mac, buy from Hakuhodo.
This brush is like The softest cotton you've ever felt on a stick! I use it for setting my under eye concealer but honestly a puff works better since you can really push the powder into the cream. It's still a really nice brush though. It's very dense and retains it's shape extremely well. I just don't use it for other things because it doesn't let go of products very well if that makes sense. W/ my other Hakuhodo brushes I can swipe it back and forth on a towel a few times and it's clean again. When I do that w/ this brush the powder still puffs out of it when I run my finger through it (I really hope this is making sense). So I just use it w/ my Ben Nye banana powder so I don't have to wash it all the time.
