I received this brush a while ago from a seller on Etsy as a gift when I placed an order. I'm trying to figure out if the knot needs to be replaced. I've never had one of these Vulfix super badger brushes so I'm not sure. To me it has zero backbone. My horse hair brush has more backbone than this thing. I don't mind the zero backbone so much. But the main thing is to me it looks like it has lost a lot of hair from the knot. I was wondering if anyone could tell from the pics i took if it has indeed lost a lot of hairs and if it's normal for the brush to have a ridiculously low amount of backbone. Also, is super badger the same as silvertip? I'm sorry if the pics don't show enough I tried taking the best pics I could. I'm hoping there is enough detail in the pics for someone to be able to tell.
