Show-me drywipe markers have been designed specifically for education, and they're trusted by thousands of schools around the globe. Each pen benefits from: a slim barrel with easy fit lid, 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 with low odour, xylene-free ink, safety airflow caps, and boast a 72-hour cap-off time to prevent drying out. This pack contains 10 medium tip drywipe markers in black ink.
