I love my Mr. Pen T-Ruler. Why? Because it's a smooth, durable metal. It has inches on one side and a flip for metrics. T is fine. What I've found with other T-rulers is that the horizontal part is built on top of the vertical. This isn't good for me because it's very easy for a craft knife to go crooked to the crevice. The plastic rulers proved to be too flimsy and move with some pressure. I use this ruler for making paper and making albums/books. Thank you for a quality product at a reasonable price.
