Cute,  quality sticker. Paper yes, Hydroflask no.
Great graphic, great sticker. However, did not stick to my hydroflask... I peeled the paper from the sticky part and placed it directly on my hydroflask and the top part of the sticker just hung off. Sticks more like a vinyl cling. Stuck to my adventure journal perfectly so, depending on your intentions... could be perfect. Very cute!
