Review on AWINNER Compatible Pencil Generation Yellow by Janet Scollins

These are the very first interchangeable tips in different colours. I have searched tirelessly. I was a bit skeptical as there were no reviews. But I pulled the trigger anyway, and I'm glad I did. It is better than springs bought before and actually fits tighter. They are responsive and accurate. The best part is that there are different colors to choose from and not just caps but real NIBS!
