I prefer the brushes with the ebony wood finish and the red ones with the black bottoms. That's just a preference though.
You should definitely get the lil' goats hair foundation blender. When I tell you that I've never met a better foundation brush, I am NOT kidding. The G257 is lovely if you just want a kick ass powder brush that blends down EVERYTHING. It's an unusual brush and does a really nice job for a heavy hand. It is NOT a light touch powder brush though. The bristles are stiff but soft.
DO NOT use it to blend foundation ... I'm still getting cussed out by the Hakuhodo lady for suggesting it 'cause I saw pixiwoo Sam doing it.
That woman was NOT happy. The bristles on the G257 are dyed, and will fade if you use it for foundations or liquid/cream products regularly. That brush is 54.00. Not a good idea to ruin it... yanno?
I tend to get Hakuhodo brushes in shapes and sizes that I find unusual and appealing. I was a big Shu Uemura brush fan prior, and I'm really impressed with Hakuhodo. Besides selling awesome brushes, their customer service is unmatched. Very nice people... very accomodating. I highly recommend it if you've got the coin to spare.
