In my opinion, the most beautiful bottle. In size, it is neither large nor small and fits everywhere. It has two disadvantages for this and the -1 star: Over time, the colored rubber on the cap loosens and comes off easily, so either you get used to it and be careful not to drop the bottle from your hands, or you remove it completely. Inside the cap, there is a clear rubber piece that if it comes off and gets lost, then it will not be watertight and water will leak from the bottle if it tilts or is upside down.
