Regarding your reply No.2,
2. I test in my lab 500,000 times is not crack. By the way, I will do it again.
Could you send me official report for us that you did 500,000times crack check test?
We did flexing test in Japan lab but your rubber boots still could not pass our request standard.
In case there are any issue about product quality, we need to get proof that we confirmed your factory product could pass our standard,
Therefore please make your lab report by official style, could you supply us within this week?
