The Staedtler Textsurfer is a super fluorescent highlighter for paper, copy and fax that will make text stand out from the page. The highlighter is inkjet safe so you don't have to worry about smudging inkjet printouts and hand written text. Each highlighter has a chisel tip which allows for marking between 1 and 5 mm, depending on the angle you hold it. You can use it to highlight inkjet printouts, laser prints and hand written text. The pigmented, water-based ink will easily wash out of clothing. Opening the Textsurfer is easy thanks to the twistable cap. Take your highlighter on the go using the inbuilt pocket clip. The highlighter is aeroplane safe with automatic pressure equalisation preventing the pen from leaking on board aircraft. The highlighters in this pack are blue coloured. There are 10 highlighters in this box.
