This is very odd bottle design I ever encountered. In the botte cap there is a glass globe or ball there that kind of plug the hole so that the water don't come out. You have to push the ball so it falls into the round part of the bottle neck there is kinda slows down the water flow a bit so you can't drink is all in one time. The bottle is kind of a replica design of ancient Chinese water bottles or medicine bottles.
The taste of it says LEMON but I really didn't taste the lemon part of it. It is a kind of very sweet kind of sugar water and not really a recommendation to drink this at all.
About the design of the shrink wrap all around is a really poor design. Just normal design I expected from any Chinese company. Not really refreshing and much too busy with too much text and not a clean design. A tip for them is really Less is More.
