Here is the E25 next to the e.l.f Powder brush to show you the size.
I just want to say Thank you so much to Sigma for this brush and I have used it a few times now and it is so soft and so easy to use and blends quite well. I am sure because its white it will get dirty fast. I will do a review once I use it for a little while.
Have you tried this brush and if so what do you think about it?
