I regret to say that the gray reference secretes a not exactly pleasant sweet smell. To wash the reference did not help and the smell is still declared to the linens. I then stored hot water bottle for 3 months on my heating on the window sill, for airing - but even that did not help.
After more than 15 months, the smell is gone, but also the square chess pattern on the cover is completely disappeared. Gebliben is a gray soft normal terms.
Even though I'm not sensitive to odors, this was nevertheless unpleasant. There are so many other great hot water bottles from Hugo Frosch, since it does not have to be real this.
Positive is to say that the clasp keeps very safe, and no water leaks.
