100% genuine. I used this for 2 days with a different lid (leak proof one) so the top straw part is unused. Has been washed but wash again when you get it. So basically new. Bought from Amazon and is genuine as there are a lot of fakes for sale. It is too big for me to travel with so have gone with a smaller size. I recommend the leak proof lids otherwise it can't go in your bag. Let me know if you want me to include this. I did use for 2 days but has also been dishwasher and cost £10 from Amazon.
