Pens with eraser

Eraser

— the pen has its own eraser. All erasers allow you to erase pencil lines, and some can even cope with pen lines (although the paper wears out a lot). The eraser on the pen is small and will not be very convenient for large amounts of drawing. However, in everyday activities where you have to deal with small drawings, it can come in handy — especially since the usual separate eraser is quite easy to lose.
