Sharpie Highlighters feature a tank style & easy gliding chisel tip for a smooth highlighting experience. The chisel tip lets you highlight both wide & narrow lines of text. Smear Guard ink is specially formulated not to smear when highlighting over many pen & inks, such as inkjet printouts, written notes, newspapers & more. Bright, see-through colors make your highlighted text easy to read. Certified AP nontoxic ink is odorless & quick-drying. Let ink dry before highlighting.
