This is a Hello Kitty metal two-tiered lunch box (^^) It's from about 25 years ago. While there is some aging, it's still usable without any problems (^^) The top tier (black) probably had an inner lid, but it's missing now. You can use it without any issues, as long as you don't put anything with liquid in it (^^) Approximate size: Height 7cm, Length 14cm, Width 7.5cm
