Is sponge-like material sticking out?
Inner walls of the refrigerator have been insulated to keep the cold air.
Therefore insulating materials are inserted during production.
How to fix
The sponge does not affect the product performance (cold air),
therefore it can be left as it is or can be removed.
The circular papers have been placed to seal the insulating materials.
Removing the papers will not affect the product performance.
