Our Hydro Flask products do not come with stickers. I hope that answers your question. **Q: Curious... is the bottle supposed to be perfectly round all the way up and down? i just received mine from amazon and it is not. it feels oblong.** A: Yes, it should be perfectly cylindrical (round) all the way up. If it's not, there is an issue, and I would think that the company would take care of it. To tell if it's in fact round, remove the cap, make sure it's empty, place it on its side on a flat surface, and roll it. **Q: I just bought this hydroflask in the color olive. Is it normal for the lid to have to be forced to close all the way? It doesnt close easily** A: How did this work out for you? I'm experiencing same problem? I know it's not normal as I have been using this brand for a couple years now. Did u keep and use? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product! *by G***Z on November 10, 2025* Stays cold for so long and I LOVE the color.
