Stealthy one
One of the best looking digital stylus out there, the Wacom One Pen supports pressure sensitivity and tilt detection. Plus, it also has a programmable shortcut button, and a battery-free design.
And with that, we conclude our list of the best Galaxy S21 stylus recommendations. I would personally recommend the official Galaxy S21 Ultra 5G S-Pen that Samsung launched alongside the device. While it lacks support for Air Gesture and Bluetooth, you can at least dock it in the official case rather than carrying it in your hands or pockets where risks of misplacing or losing it are really high. Plus, I am actually digging the slightly larger footprint as it makes the stylus more comfortable to use compared to the relatively thin stylus that you get with the Galaxy Note series phones.
