Recommend me a retractable powder brush

[KatyS36]

Hello. As per title can anyone recommend me a retractable powder brush?
Thinking this would be a lot more convenient for travel as a powder brush is often the only one I take.
I've just has a look at the body shop one but it is quite stiff and narrow. I'd like a fluffy brush.
Budget is flexible.
Thanks Katy

I like the Eco Tools one. You can get it from Boots for about £9 I think. The bristles are soft and don't fall out, unlike my other one a crap Boujois brush.
