Now it's the $4.50 bento lunch box hack that has parents going wild.
A user on Facebook posted the clever hack on her page almost a week ago, and now the post has been shared hundreds of times.
The DIY bento lunch box is quite simple to put together.
The hack was originally posted by Amanda Hale who added that she trimmed the edges off the ice cube tray so that it would fit perfectly into the clip container.
Parents are already rushing into stores to get their little ones the makeshift lunch box, with some saying that it's a really clever way to make lunches more interesting for kids as well as controlling portion sizes.
