Never worry about smearing your notes again! This highlighter uses a special ink formula that binds with water-based ink, such as ballpoint and gel ink, which prevents smudging when highlighting over written notes. The soft chisel tip flexes to make perfect contact with the page, giving you neat, 3.5–4 mm wide lines without having to hold the highlighter at the perfect angle. It also works great on curved surfaces like the pages of a thick textbook.
