I tried 3 different kabukis before I found the perfect one. It's from an ebay store, Forever Female, and it's called the Ultimate Kabuki Finest Available--it says it's 100% guaranteed or your money back. It's $16.50, plus you can get the cutest brown leather case for it for $7.50, so it keeps its shape real well. It is fantastic!!! I mean, MAC quality! The BE brush felt like needles poking my face, another one shed too much, and the other didn't seem full enough.
I heard about this brush on Mineral Makeup Mania---I'm so glad I tried it!!
The store does have a few kabukis, but the right one is $16.50.
