The Bion 9184 is a practical highlighter designed for school, office, or study environments. It features a 5.15 mm chisel nib that allows you to switch between broad and fine lines depending on the text you are marking. Its fast-drying ink ensures a uniform application without smudging your documents, while the non-toxic formula makes it safe for daily use. The ergonomic body is shaped to fit comfortably in your hand during long reading sessions, and you can choose from yellow, green, blue, or orange colors to organize your notes.
