Show-me drywipe pens have been designed specifically for schools, and they're trusted by thousands of schools around the globe. Each pen has been designed for use by small hands in the busy classroom, and benefits from: a slim barrel with easy fit lid that is easy for children to use, an extra-hard nib that will not easily splay out, and nib-stop that prevents the tip from being pushed into the barrel. They're safety optimised too, with low odour, xylene-free ink, safety air flow caps, and a 24-hour cap-off time to prevent drying out. Medium Tip. 10 Assorted Colours. Excellent quality designed for wear and tear in the classroom. Pack 10.
