This Itoya erasable pen has a sleek design that makes it easy to identify the color of the ink because the color of the shell matches the color of the ink. This, coupled with the fact that the ink writes as well as any ballpoint pen I’ve used but erases so well that it leaves no trace, makes the pen a highly desirable product that is suitable for anyone who ever has to write something down! It fits easily in your pocket or in a pencil case.
