Tupperware lunch box Size: 20cm x 13.5cm x 5cm Side dish container (with lid, 200ml) This lunch box is no longer sold, but it is a sealed container, making it easy to carry. To open, press both sides as shown in the 4th image. I couldn't find the instructions, but it has been kept in a bag and is very clean! The color is close to the bush warbler green shown in the 2nd image. Thank you!
