Review on 📏 Accurate and Durable: Helix Plastic T-Square Inch 20002 – Perfect for Precise Measurements and Drawing by Scott Tompkins

I wanted a small T-square for road drawing board (Masonite) and I needed about 14 inches. Of course, I can shorten this much better than I can lengthen a 12-inch. It's transparent blue and I would have preferred it to be transparent but I knew I was ordering from the description. I like it.
