This is a popular vacuum storage container for storing rice. It seems the vacuum function of the lid is not working and is broken. It seems that sometimes you can create a vacuum by pressing the center of the lid during vacuuming, but it is a junk item. Since I haven't actually used it to store anything inside, I've listed it as "like new." I hope someone who understands this will appreciate it and use it as a stylish stainless steel container and a small storage container.
