I prefer this jam not only because the quality is good, but also because I can open the lids easily and without effort. I also use them to fill my home-made jam, but I just can't understand why these jars have to have a plastic label, which 1. is almost impossible to remove and 2. has been stuck on with a synthetic glue. You can't even remove this glue with petroleum ether, so I have to dispose of them - what a shame! Migros keeps claiming how green and ecological it is. But that's where it falls short. You could also use paper labels and a water-soluble glue without compromising on quality. You could also sell these jars empty during the preserving season. That won't happen either. Christine Stäuble
