Penco Drafting Scale Ruler

By Penco. 

The Penco Drafting Scale is a practical and stylish sketching tool. 15cm long and made from aluminium, this drafting scale is both functional and sturdy.

Note: This product has a scale of up to 1/100-1/600, but we do not recommend using it in situations where precise measurement is required in a professional setting, for example in the use of an architect's project.
