I was excited to try the bento box but it arrived with with one of the locks broken Other thing that I don't like about the product is only the top lid is airtight, the lower boxes are not so lower boxes are good for non-spilling food
I bought a 3 tier box. This set is so fragile. I took it out of the box and accidentally dropped it on my counter, like 10 inches drop, the buckle on one tier broke!! Alrt, my bad... I tried to use the other two. I put the food in piping hot into the bottom box and closed it immdly. After 30 mins, yes 30 min.. it was pretty much ice cold!!!! good for nothing.. absolute waste of money!!!!!!!!
