Now this brush isn't the Buffing brush, personally I think it's a mix between the Stippling and the Buffing brush. It has dense bristles like the Buffing brush and is slightly larger than the Stippling brush. I do like applying my foundation with this brush but find it takes slightly longer to work my foundation into my skin. The Buffing brush is larger so I find that it's quicker to apply my base.
The brush is really cute and compact, great size for travelling and as good quality as the rest. This is really good for getting into little areas such as under the eyes, side of the nose and under the nose. For areas such as cheeks and forehead, it takes more work.
As much as I have enjoyed using this brush and it's great, I don't quite love it as much as the Buffing brush, which means I'll have to buy a new set and find a use for the duplicate brushes I'll have.
The Real Techniques brushes are available online or in Boots stores.
