Ok 2 questions

1. My friend bought me a Silvertip brush from AOS and i wanted to know if there was a way to figure out how big the knot it. AOS has no info on knot size on their website and i can't really aske the sales man (idk that he would know anyway)

2. The brushes are meant to be hung bristles down, correct? Why is the branding/labling therefore upside-down?
