Love Sigma but have some complaints

Well first of all i have to say that I really do love Sigma brushes. I own the complete set and the kabuki brush, they all work really nice.
So couple days ago i was going to use liquid foundation with the ss187 and guess what the brush hold started to get loose, and the thing is I haven't been using this brush a lot and I also did wash it righ, I always do it really carefully so that the water doesn't come in to the area... but well
thank God I could still fix it i took some glue from my dad put it on the area where it started getting loose, after 24 hours drying it was almost perfekt again, u just can see a bit of glue on the brushhold.... so I'm kind of disappointed now...


One more thing why I want to complain a bit about Sigma are the new brushes.
The thing is I would like to have some of the brushes from the new set but not all of them, but they don't sell them seperatly!! sooo I'm really sad.... I wish they will sell them seperatly in the future!!!

because I still do love their brushes
