100% authentic Stanley bought new from the Stanley website. Love the Protour design and it’s great at keeping your water ice cold, but I bought too many and it’s just taking up space. I only used it once, so it’s in like-new condition. It has the original straw and I will include a metallic blue boot that I got to go on it. Thanks for looking! Please feel free to ask questions!
