The “removable marker” is a film tape-style line marker that allows you to draw lines without worrying about ink stains, and you can also “erase” them later, making it easier than ever to draw lines. Unlike conventional ink-based line markers, it doesn’t have common issues like ink stains, uneven coloring, bleed-through, or smudging of text. You can draw straight and uniform lines, and you can remove unnecessary lines to “erase” them. This allows you to use a line marker with ease while keeping your paper clean and tidy like never before.
