I buy the Natura dumplings now regularly. The birds scramble for the dumplings and clean this in a few hours to the last crumbs off. In other dumplings the networks are always at the latest when the first blackbirds have served the dumplings, snapped. This phenomenon I have not yet observed in the Natura dumplings, therefore appear to be very well sealed. the bucket itself is very stable and has a carrying handle, and the shipping always ran off to my satisfaction.
