Review on 50Pcs Hot Disney Cartoon Winnie The Pooh Tigger Eeyore Stickers - Vinyl Waterproof Graffiti Patches for Water Bottles, Laptop, Car, and More! by Hannah Curi

My daughter put them on top of her hydroflask and had trouble applying them, we just smoothed them down further so they were flush with the bottle and the next morning it looked that way from like. Tried flattening them again to no avail. Not sure if there is something in the hydro flask that is preventing it from sticking but this is her second hydro flask and the other one is covered in stickers and neither of them had any sticking issues. If you see a side view of a mermaid decal that is completely flush with the bottle, that decal is from a different range of decals, no problem with that. Maybe apply a warning not to buy for hydroflask.
