Whether you’re still a young minifig or a grown Mindstorms expert, the officially licensed LEGO lunchbox is for you. The eight-stud container-brick measures approx. 3″x 4″ x 8″. I’m not sure if it interlocks with other LEGO lunchboxes though.
You can order the LEGO Lunchbox from Firebox for £9.99 (approx. $16 (USD)). It’s available in pink, black, red and blue. If you want to go Xzibit on your LEGO collection, you can get these LEGO Storage Bricks, and replace your juice box with a minifig.
