I have now weighed the whole package of the article alone with my kitchen scales. It is 1363g. As I read, there may be a maximum deviation of 80g (wrong item received method).

The variance In weight Is minimal, so It's fine.

With the sealed box method, I am having trouble getting the seal off. There is a white strip on the item.

Try using a hair dryer and a thin blade.

If need be, take an entire day. It can be done.
