Just bought this at Macy's. It looked good in the store, but doesn't look right at home. (I should've stuck with my old standby, Mocha Pink.)
Because of the way the product is packaged, you could not substitute another brush, but I only ran it across my face very lightly (I don't use much blush) a couple of times. I think it would be fine with a quick wash.
Retails for $21.50. I'd be glad to recover even a small amount of money for a purchase that turned out to be a mistake for me.
