SHISEIDO Lip Brush (Black) 403

This is exactly the flat brush I was looking for. It has a firm texture and is very easy to apply with. I think it would be even more popular if it came in cute colors like pink other than black.

I bought this because the lipstick I was using was no longer coming out properly. The brush tip is soft and it's very easy to apply!

I lost my Shu Uemura portable lip brush that I had been using for about 20 years, and this one had pretty good reviews, so I bought it. It seems to have less stiffness than the one I was using before, but considering the price difference, I think it's within my acceptable range.

I bought this because I wanted to master lipsticks that are too pigmented and difficult to use. You can adjust the color as you wet it, and it comes with a cap so it doesn't get dusty during storage.

It's compact and incredibly easy to use. I think it's better to apply lipstick with a lip brush.
