What if earloop are purchased in large quantities? How to judge the quality of earloop in large quantities?

 

Sampling and testing: After purchasing in large quantities, the first thing to do is to test the earloop, elasticity, material, report testing, etc., don't wait for the problem when you get on the machine;

 

Be sure to let the manufacturer send samples to you, and receive the goods according to the quality of the samples;

 

Sign a contract with the manufacturer to deal with the follow-up problem of substandard quality;
