Bdellium Tools 固态化妆刷清洁皂 - 海洋微风香型（蓝色）带清洁垫，适用于专业化妆师和日常化妆刷清洁

I love having a brush cleaner “kit” like this. It’s compact and very effective. The scrub side of the lid works well with small and big brushes. Also, easy for travel to pack this up and go. I’ve had mine for almost a year and the soap bar is still staying strong (maybe 1/4 smaller than it was when I got it due to using it).
