Drafting scale, black
Beautifully machined colour anodised aluminium metric triangular drafting or architects scales from Japan. With metre scales in 1:100 which doubles as a standard 15cm millimetre marked rule); 1:200 (usefully marked in half-millimetres); 1:300; 1:400; 1:500; and 1:600. Obviously useful for architects, designers, indeed anyone who might wish to produce accurate scale drawings, these are too perfect not to want to use as simple, compact, and uncommonly accurate desk or workshop rules. 15cm, black anodised.
