Makeup brushes too scratchy?

Hello =)

So I'm not sure if some of you have had this experience before...

Sometimes when you use your eyeshadow brush, it just feels too rough and scratches your eyelid and really hurts?

That happened to me before and also happened to my friends who I was applying makeup on, so I'm pretty sure it's not me being overly sensitive, it's the quality of the brush. And the brushes in question are actually not some of the cheap brushes either-- they're my MAC 219 pencil brush and 217 blending brush =( which is very frustrating considering the amount of money I paid for them, the quality should be so much better (even my StudioTools and Sonia Kashuk brushes are softer and they're 1/3 of the price).

Anyways, I found a little trick that helped =D

All you need is a nail file lol! And make sure it's the rougher kind (you can even use a sand paper if you wish). And you just take your brush and brush it back and forth on the nail file. Brush your lid to see if it's still rough/where it is rough, and just keep doing it until the scratchy bristles are filed off =) Don't forget to wash your brush after you're done!

I'd like to say don't worry if this is gonna ruin your brush... because my brushes still perform the way they are, and my 219 actually hasn't bothered me anymore =) 217 sometimes still scratch a little but it's definitely softer now.

Hope this trick helps some of you =)
