Penko's scale tool with bold coloring on the triangular scale for drafting. While maintaining the functional beauty unique to drafting equipment, we use highly durable aluminum to create a ruler that is perfect for everyday use. The beautiful slender body does not take up width even when placed in a pencil case. Also, the ruler is usually flat, but this is triangular in shape, so it is easy to pinch even if you put it on your desk. Simple and practical. This is an item you should have on hand.
