In March 2018, we held a campaign for a limited supply of  Clip Studio Paint Pro, our illustration, comic, and animation software, to be provided with purchases of the HP Spectre x360 from HP Directplus.

The HP Spectre x360 is a 2-in-1 PC with a 360-degree hinge that comes with the HP Active Pen as an optional feature. With 1024 levels of pen pressure sensitivity, it allows you to add fine details to your illustrations. The pen tip and the screen have just the right amount of friction, little slippage, and feels just like drawing on paper. You can also flip the screen into tablet mode using the 360-degree hinge to focus completely on your creations.
