I also bought this brush when I got Cle de Peau's concealer. I love how this brush applies the concealer, blends it in smoothly and evenly. I've used this brush daily for over a year and it has retained it's shape perfectly. Fantastic brush!

I bought this when I bought my Cle de Peau concealer. The MA used it to apply the concealer on me and I loved it. I had no idea Shiseido made such great brushes! I have used every kind of expensive brush out there (Trish, Shu, etc etc) and this is my favorite concealer brush.

I bought this brush w/ my Shiseido concealer(and actually confused the recs about Shu Uemura brushes)(Duh)
but I really like it! I suspect the bristles are synthetic(probably taklon) and are perfect for applying concealer sheerly in eye area w/out having to rub (I still tap it w/fingertips to set).I also have started to use it to apply foundation where my pores are the most pronounced(nose) to coat them more evenly and give a smoother finish.This brush seems very durable and has not changed shape and I wash it every day.($20 @ Nordstroms)Would re-purchase if need be.
