September 12th. To update. These bottles are not what I thought. Many thanks to the seller for sending another set. But I regret to say that these bottles are made very cheaply. The cover is very cheesy. In any case, it's not very durable. Lid, Lud breaks very quickly. The white part attached to the red part is already torn off. Then the red part that sealed the bottle split in two. I took all four bottles and threw them in the bin.
