Aluminium Folding Desk Ruler, Dark Brown

A rather neat dark brown anodised extruded and precision ground aluminium folding desk top ruler from Japan. Ideally sized at 15cm to fit easily into a pencil case, box, handbag or breast pocket, these fold out to form a full standard 30cm rule and straight edge for draughting or cutting. The pivot is also marked at fifteen degree intervals for use as an approximate measure for interior or exterior angles, either on paper or for carpentry and DIY.
