Thomann Cleaning Set Trumpet

The set is OK, but two issues cost the 2 missing stars:
1) the storage container is a small plastic tube, which is good because it is small, but it is bad as it can squish the brushes in a manner that the britles get "combed", thus exposing the metal axis (potentially harmful to the brass' lacquer);
2) the cloth comes in a good size but the fabric kind of dismantles itself, that is, it drops granules of cloth which, for me, leaves the instrument dirtier. I had to wash it twice and it still drops these small clothpieces.
