Big enough for a 30cm ruler, this Clear 1.5L Pencil/Stationery Box from Really Useful is ideal for storage of all your stationery supplies. Measuring 100x355x70mm, it provides plenty of space for pens, pencils, rubbers, rulers and other essential stationery. The lid locks securely to keep everything neatly contained, and is also clear to clearly show the contents - great for a well-organised desk or drawer.
