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

This T-angle cannot be used for measuring! Inches and cm do not start at the edge of the T! There's a space, and even then the strings for inches don't even start with 0! It's almost useless to me. For example, if you just want to align an edge and draw a horizontal straight line on paper, that's all it's good for.
