However, there are flaws in the tunnels:
I had some major issues when screwing eingier tunnel. The threads are therefore partly anything but smoothly.
Below point I will not be included in my review and mention it only for a better description of the item: The little tunnel (2, 3 mm) have no through hole which the inner rod is clear as to detect closed.
The appearance fits nevertheless quite the same as the photo.
Even though I have always managed after several attempts to open the tunnel again I will not stay permanently in this set. Nevertheless, the price for this set is appropriate and gives not a bad commodity at a more than fair price.
