Best brush for concealing under the eyes +

I have been using a normal foundation brush as a concealer because it is large and easy to use compared to the normal standard sized ones. However, it is a pain at the same time because it doesn't fit into my Benefit Erase Paste concealer jar. I am so excited I got a nice delivery today from Sigma cosmetics - the new F65 large concealer brush!

It feels fantastic and is the perfect size - cannot wait to use it! It was us$14 and with the Aussie dollar going so well its a great time to order goodies from the US!
