This is a beautiful idea!   Not only is this a drink bottle, but it has a screw on container on the bottom, this container could be used as a cup when you have finished eating what ever was put in it for your lunch or morning tea.   The straw at the top is protected from germs, when not being used, by the push down cap, that you can see in the picture.   The bottle has a clip on strap, so it can be carried with ease.   To round of the whole package, it's adorned with Shirley Barber's beautifully illustrated artwork.
