🔷 Irwin Tools 12-Inch Combination Square with ABS-Body in Blue (1794470) - Efficient and Accurate Measuring Tool Review

I'm really surprised at how cheaply it's made, especially the plastic part. Don't drop it. Funny, I could buy it from Harbor Freight then.

I had a small project to complete. It worked. I still use it as a ruler/drawing. But there is no other use for me. It was well built for mass production, with no gaps.

"ABS case". that means ABS plastic (Acrylonitrile Butadiene Styrene) so you end up with a plastic square. I used a good quality square to test the squareness of this device. At room temperature it was fine. Later, after the area was under direct sunlight for some time, it was no longer square. In another opinion, the description should be "plastic case" or "ABS plastic case" because "ABS case is not very simple.
