This is by far one of the best eyeliner brushes I have ever used! And trust me I have tried many.
This one is by Studio Basic and it can be found in most department stores or drug stores and you can expect to spend around $8.00 on this brush. It will outdo any that I have tried by Bobbi Brown, Mac, Avon and more.
It has angled bristles that are not too firm or too soft, and this allows the perfect application of eyeliner, powdered or wet liners.
To clean it could not be easier, just use mild soap and warm water and allow it to air dry and it is as good as new.
I actually found my last ones on sale at Rite Aid for 50% off!! I bought two for the normal price of one, but they do last a really long time so the last two I bought are still in the package.
I would honestly say this brush gets a 5 out of 5 rating, I love it!
