Kill Zone storage bin

I am looking for a bin that can fit a 11 1/4” x 15” folded kill team board with not too much room around it. It needs to have a bit of depth to store built terrain on top of the board. I would prefer clear plastic, so it’s easy to see what’s in it, but opague will do.

I’m in the USA, so I’m looking for bins that are available States-side.

Has anyone found such a kill team kill zone storage solution?
