Over the years I've stopped using any drawing boards and T-squares, but have continued to use the 12 inch plastic stock for my home projects, including boards for measuring measured distances and right angle marking. It was just cheap hard plastic, probably bought many years ago for less than a dollar. It broke and I was looking for a replacement. These purchased T-Squares were my hope for a replacement. Not closed. First, the T-end is so flat (thin) that it doesn't stick to the edge of boards. I can't even hold it tight enough for it to pop out and turn crooked. I can't use it to measure or mark right angles without a solid base on the board. the problem of instability, the plastic is so flexible that if you draw a straight line with a pencil it will bend. For example, swipe the top edge and the line will fall towards the end of the ruler. I think it bends, so how about more unbreakability, but not a good idea. I'm still looking for the cheap, durable one I had. L After all, I can only see with one eye and he has no central vision, plus glaucoma. So I need contrasting lines and numbers to see them.
