Although the magnetic design of the pen holder provided by Microsoft SP4 is cute, its actual effect is not enough to completely prevent the pen from falling everywhere. I hope to find a more reliable way to fix the pen holder, so that even when I leave the coffee shop, I can rest assured that the pen will still be in my hand.

The design of this pen holder is very simple, but it can firmly fix the fountain pen. By using 0.1 mm thick acrylic double-sided tape to stick the buckle on the tablet, it can be easily installed.
