The Wallien is nice and the colour moon beautiful but it has a hole in the middle of the sleeve which is not nice. They have told me it is to drain the water but it seems as if it was broken or burnt by a cigarette. I don´t understand why they put that hole in the middle of the sleeve. It had also some little stains. I decided to keep it because I has already changed once the size as the 4 was too small. The 6 fits good.
