This is a Shu Uemura brush. I bought it about 5 years ago. I used it about 10 times to apply liquid foundation. Since I don't use liquid foundation very often, I used it for about 3 months for a different purpose: washing the ball after clay packing. I washed it, so the Shu Uemura logo has disappeared, but it is a genuine product. I forgot where I bought it, but I purchased it at a store near Tokyo Station or Ginza!
