This lunchbox has a large compartment that can hold a whole sandwich. It also comes with a gel cooler pack that can be placed underneath the tray to keep food fresher and cooler for longer. If you remove the sandwich tray, the compartment can be used to store pasta or salads. The lunchbox also has leak-proof silicone seals that secure wet foods, such as watermelon and yogurt. The seals are removable for easy cleaning and prevent mold buildup.
