Mini Pink Organic Cotton Hot Water Bottle

I brought the bigger version of this hot water bottle which I so love ,this one is cute but too small it hardly holds any water,first time filling it up the water shot out of the top and burnt my hand,it only holds a small cup of water,it's misleading the volume that it states,it's no where near that, I don't use it,bit disappointing as it did cost a bit other than that I absolutely love COSY PANDA,I have a few now and very happy with the others.
