Review on AWINNER Compatible Pencil Generation Yellow by James Dominick

These are the very first real interchangeable pen tips in different colours. I 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!
