this is really stupid and probably all of you may have figured this one out.
yesterday, my fried's mom who is an artist heard my complaint about my detailing brushes going limp, so she bought me 4 $12 dollar ones - which is really nice!- but the protectors weren't there, so i took a straw and pu it over the bristle like the normal ones.
see what I meant when I said this was really stupid?
