ISO Container/Bin 7x8x5

Looking for a plain bin/container that is plastic and around these dimensions 7x8x5, doesn't have to be exact, but must be around 5'' deep cause I need it to hold water. Open to trading for a small item on my profile.

No holes, or branding/patterns. Could just run to the dollarstore but hoping I don't need to consume more plastic if there are plenty things out there already. I've been using a salad box container but plastic is a bit too flimsy to hold water.
