Used for a 3-month long art project. Very useful for taking notes. New AAAA battery included. Additional points and tool included. The Dell Premium Active Pen is the first active pen that offers multi-protocol compatibility including AES 2.0. Create strokes of varying lightness or darkness, with low lag, and detailed shading thanks to AES 2.0’s 4096 levels of pressure sensitivity, 240Hz report rate and tilt support on Dell 2-in-1 notebooks with Wacom AES 2.0 technology. Rest your palm comfortably on the screen when you work and you’ll be safe from potential errors thanks to palm rejection technology. The magnetic pen securely attaches to the side of your 2-in-1 on supported Dell 2-in-1 notebooks.
