Insulation is applied to the inner wall of the refrigerator in order to preserve cold air.
Therefore, insulation (foam) is injected in the manufacturing process.
Since insulation (foam) is absolutely irrelevant to the cold air production (performance) of the refrigerator, there is no problem with the product, even if it is left as it is or removed.
The round paper attached to the back of the product covers the insulation (foam) injection hole.
Use it as it is.
