Multi Coloured Pens

The case for these is anywhere you switch colour constantly: marking student work, colour-coding a roster, annotating a plan. One barrel means nothing gets put down and lost mid-task. The trade-off is girth, since four refills need a wider body than one, which suits an adult hand more than a small one. Check refills are available before standardising.
