Lid is BPA free. Food grade stainless steel.
I just bought one from Target Epping, VIC. NB: The bottle is really thin and light.
The last bottle I purchased was a Cheeki (500ml i think) from a deal posted here! It was stronger/more durable, so I much preferred that one, but at $8 for a 750ml bottle, I think this one is a great deal.
I think that bottle will replace the plastic one I have at work. The only thing is that I wont be able to squeeze it - well not more than once I supose.
