Big enough to hold a lunch size portion of that amazing pasta you made the other night and small enough to fit into your insulated lunch bag. OK for wetter foods like dressed salads or dips but not suitable for liquids like soups, tea or coffee...or for transporting goldfish. Silicone seal inside the lid to help prevent leaks. Levered locking clips to keep lid on tight. Folded smooth edges. Weve also included a spare seal inside the box. Were nice like that. Capacity: 675ml. Weight: 326g. Leak Resistant Lunch Box. Material: Stainless Steel (201). You can also get a moveable divider, which let you split your lunch box however you choose and a replacement seal is available in case you need another! Made responsibly by our producer in India from high quality 201 food grade stainless steel.
