Review on 🛠️ Tulead Precision Woodworking Machinist Tool - 50x40mm by Carlos Deuschle

My calipers are a cheap set but I trust them enough to make an offset of record 1 mm. Either this square is 49 x 40 or 50 x 41 and my calipers are wrong, in either case it's 1mm different. This isn't a problem for me as I use it to check the squareness of my builds, but could be a problem for anyone using it to check their measurements. I'm knocking off the stars since it's supposed to be a precision square (though I don't know what I was expecting for $10). Ignore the glue and scratches in the picture, I've already started using this in my builds and only found out about the sizes when I got bored and checked it out one night
