Here is a good example of a poorly manufactured product .. The box does not close because the height is too fair, unlike the 7.5 cm 8 cm announced. Small standard vials 10 ml HE fail to close the box! I note that the format is standard vials, whatever the HE provider, I have several suppliers, they all have the same dimension. So it is a topic related to the box whose size is too rough and not controlled. I advise, I'll look for another more serious box provider.
