The Staedtler Noris digital Jumbo Stylus is not compatible with the HP Envy x360 unless the device has a special EMR (Electromagnetic Resonance) digitiser technology. The Noris digital Jumbo Stylus only works with displays that have an EMR digitiser, which is not the case with most HP Envy x360 models. It is therefore important to check whether the specific device supports this technology before purchasing.
