The patterning of the cover is - compared to the image - barely noticeable (which I like better); the gray has an unmistakable tinge of blue (which I'm used to).
The hot water bottle in itself makes a very reliable and stable impression and is thanks to the large handle excellent seal.
Note for sensitive noses: the (to me not too unpleasant) odor of the bottle decreases progressively with each use.
