Is it like an overseas refrigerator? I found an item called "Drink Pack Cover" at the 300 yen shop "3COINS", so I tried it.
A special cover that completely wraps milk and juice in a paper carton. It is compatible with general 1000ml (33.81us fl oz) packs, but please note that the top of products with a cap type spout will not close.
With a snap button on the top to prevent oxidation. The spout is closed tightly, and when you drink it, you can pour it without removing it from the cover by removing the button.
There are two types of designs that you can choose according to your taste, both with "MILK" and "JUICE" labels. It's made of PVC, so even if it gets dirty, it can be easily wiped off or washed with water. Why don't you incorporate your favorite cover as if it were an interior?
