All pieces are too small! 9.3 mm on lower and 9.5 mm on greater diameter IS NOT 10mm! When you buy something you expect the exact diameter or at least a little bigger, never lower like 0.5 mm. 0.5 in diameter is a decisive difference when you talk about diameter. Will not work on my project! Other users are saying: "Too small" pay attention to the comments and correct the measurement.
This is not a gold plate
