NicPro mechanical pencils

Hey everyone, I am brand new to anything like this. I recently bought some mechanical pencils that are nicer than I'm used to. I bought them because I've taken up noveling by hand and saw it as a worthy investment. Now undoubtedly it is. I bought the NicPro metal mechanical pencils on Amazon, they were really well priced and I see them as good quality. Should I invest further? Try out nicer pencils? Would it be worth it in your opinion? Where should I look? Any opinions on this would be awesome.
