I should have been more careful

Seeing "60 mm", I expected to see a sheath able to group a power cable, an Ethernet cable, a cable screen and multiple USB cables without worry.
Unfortunately, the jacket is really too small / narrow.
As delivered, it has actually a 6mm diameter, allowing just 2 USB link cables purposes.
It is of course "business" to include several cables, but suddenly the width of the band is too low to ensure a semblance of rigidity.

In short, I am disappointed, and I should be more attentive to the visual ..
