This is a GoFlex collapsible food container with a bellows-like body that allows it to be folded. Size: Approximately 20.5 x 16.5 cm Height: Approximately 8 cm (max) to 2 cm Capacity: 850ml (Height can be adjusted to match the capacity) I received three new ones and have been storing them. I took one out of the bag and extended the bellows to check the size, so I disinfected it with alcohol. Please refrain from purchasing if you are concerned. The instruction manual has some creases. Please forgive any other oversights. I would appreciate it if you could understand that these items have been stored at home by a private individual.
