A secondhand jigsaw puzzle with no guiding picture fitted perfectly into the pouch and delighted my puzzle-addicted granddaughter!
Copper Water Bottle Blue Rose
These are a bit on the large side holding 1 litre of of water so too large to fit in a car drink holder. You need to decant into a smaller bottle which in a way defeats the purpose of the bottle. Regarding health benefits that would have to come at a later stage but I am sceptical.
