The concealer brush has a short handle, much shorter than other brushes I'm used to but it actually feels lovely in the hand and is easy to manipulate. The bristles are synthetic and shaped in a tapered, flat paddle formation. I found it a little scratchy on the eye area until I had washed it (note to self: always wash brushes before using) and I've had no trouble since. The brush gives just the right level of resistance to make concealer blend seamlessly without rubbing any off. It's like magic packaged in a velvet pouch!
I use it on the undereye area and on blemishes and it works well for both. I actually prefer it to using my finger on blemishes now. I feel like I might have been converted.
Le Métier de Beauté is only available in the States at the moment and the concealer brush costs $50. It is possible to order from Nordstrom for delivery to the UK, their shipping costs include any customs fees but it's a fairly expensive service. Alternatively you might like to call in a favour from a friend.
