Nonsense.
This small case solves my problem. Now I wrap the cord a few times around the finger and finally two times around itself (this creates a kind of 8 ... well, you would wind up wiem halt a band) and I put then in this case. No matter what I do: I open the case again, everything is still nice wound, clean and can be used immediately.
The material the case is processed sensational quality (I want to know at all how they can offer such low prices?), The zipper is high quality, stain-resistant. In case would be even a Klein mesh pocket ... (I do not need). And the case looks good ...
That must have one!
