I build craftsman building kits for my model railroad. These are great for getting walls at right angles. I’m not sure how I built without them!

I use them for building model airplanes. I use them as weights and for square blocks to hold things square while glue dries. Quality is good. I have 4 sets of them and they are all identical.

Bought these to check calibration of a depth micrometer. Won’t work as they are not as accurate as advertise.
