Our dome-shaped lunch box in silver color is reminiscent of the Construction Worker lunch boxes from the 1950s, but made of a lighter gauge tin. This one is made primarily for customizing and promotional use. If you're looking for a daily-use industrial lunch box, please consider our Construction Worker Lunch Boxes. Our Plain Metal Dome Lunch Box in Silver can be used to store things, to decorate, or to carry a very light duty lunch. It also works great for weddings, promotions, events, or creative gift packaging. Case pack of 12 lunch boxes available for $12.90 per lunchbox with free USA ground shipping here: Bulk Case-Pack.
