I don’t see any indication of the quality.
No “T5”, “T10”,…either .
How do you judge that it’s “top quality”?
Any word if they are rolled or ground?

we are the factory of thes products low price with good quality :slight_smile:

OMG is not a great way to introduce a marketing post, it makes it seem as if you’re pretending to be a user rather than the manufacturer.

I have to agree with Pete here. And if you tout any form of quality, you need to state the tolerances and ratings. Along with the guarantee you have regarding these tolerances.
