The Pen2 Pro is a magnetic stylus with 4,096 levels of pressure sensitivity that provides a handwriting experience similar to that of paper. You can easily erase the strokes with the eraser on the bottom, just like you would on a sheet of paper. The shaft also offers an ergonomic grip and allows you to take notes comfortably. It is compatible with all BOOX ePaper tablets and tablet PCs that support handwriting. However, it can only be attached to the side of devices with a magnetic case, such as the Tab Ultra tablet PCs, Tab Mini C, Note Air tablets, and Nova Air tablets.
