Parmigiano Freshness-saving Glass Cheese Holder box bowl with Vacuum Seal - EMILIA FOOD LOVE Selected with love in Italy

Bought this cheese holder for me and as a gift. Loved

I thought at first when I pressed on it there was a suction but the more I used it, I realized it wasnot suctioning. I went to pick it up and the top just comes off loose. I paid a lot for it and I am disappointed that it doesn't work.
