The best: the cable tie itself is directly attached to the cable (with a loop device) - so that it does not is lying around loose and can be lost.
Very well thought out solution! Good, stable material.
Is there the manufacturer Brennenstuhl in black or white; and in the different lengths of 12.5 cm length and 20.0 cm length (the length should rather buy something 'too long' - because Ruckzuck the length already depleted during fixing, especially with thicker cables (if necessary you can supernatant / disturbing lengths still with scissors cut).
Comparable products are also available from Hama (PC accessories specialist) - after my price comparisons but they are significantly more expensive (or less pieces in 1 pack) - without my having a better quality of the Hama-models may find (got the but not himself had in his hand, but only the reviews read here on Amazon / compare). Brennenstuhl is definitely (also) a good branded product with quality.
