Super induction: The lower friction of this titanium tip makes it a little easier to write fast. Non destructible nibs: This replacement surface pro tips may possibly cause less wear to the screen because it seems to have much less friction involved and only a light touch of the pen is needed. Smooth slim: The feeling drawing or writing with these is like pen on paper! Saving more money: It will stop replacing nibs for your surface pen. How to install: File with the side of it flat along the file, apply a little bit of pressure, as this is titanium, and it will scrape off ever so slightly. Once you notice a VERY slight flatness to one side, try pressing it in, but do not force it. If that doesn't work, try filing down the side opposite to the one you just did. Reliability: No need to worry about scratching your Surface pro screen with the metal tip, it can avoid to replace the plastic surface pen tips breaking day after day.
