Multi Ruler from Midori. A Multi Ruler? What's that?

Well, it's a ruler that is just 150mm long, but opens out to double its length! The pivot in the middle, which enables the ruler to be folded in half, is also a tiny protractor, so you can use it to measure angles as well as length.

Made of translucent coloured plastic, joined with a metal rivet. Dimensions when closed: 150mm x 25mm, ideal for tucking into pencil cases.
