I have the box in size M bought for my Eurasier (51cm, 18kg) and it is just right in size. From a processing perspective, my box like good and the colors are displayed as - the price-performance ratio is absolutely right. The box is supplied with 4 pegs and a carry bag. The only little problem and the reason why I have only given four stars is that the box is very difficult to establish at the beginning. The material is very tight and I really had to use force in order to put together the rods can. After the box has been standing up a few hours, the material had apparently gedeht and now they can be set up much easier. You have to overcome only at the beginning, then you have a nice, stable transport box.
