During the unpacking however, the butter brick is generally held by a hand which results in greasy fingers.

Another disadvantage of such wrap packaging resides in the fact that it is only folded around the butter brick in a non-airtight manner so that, particularly in the corner sections, unappetizing yellow areas develop by exposure to air already during storage on a store shelf.
