HP MPP Active Pen, compatible with 4096 levels of pressure sensitivity. This pen was included with an HP Spectre laptop, but I am selling it because I don't use it. The standalone price seems to be around 10,000 yen. I'm not sure if it works with Apple products. It's black and cool, and I was thinking of using it with my iPad, but I decided to stick with the official Apple pen and haven't used this one. - Model Name: HP MPP Active Pen - Color: Black - Accessories: 2 replacement nibs - Features: 4096 levels of pressure sensitivity - Compatibility: Microsoft Pen Protocol 2.0 Thank you for looking.
