Review on Alexandra Replacement Surface Pen Tips (3 × HB, Default Tip) for Microsoft Surface Pen Model 1776 and Surface Pro 4 Pen by Vijay Patel

I'm a math teacher who checks these pens for constant use and falls. These are the best tips I've found so far. I have to remember to rotate the tip every few days or if I hold it at the same angle every day the pen will tip over. Still, it's just as good as the one that came with the pen, so I'll definitely be buying more!
