the local shop was out of the frozen fish food cubes ( I usually keep brine shrimp an blood worms in the freezer for food rotation ) what the shop had was frozen sheets of blood worms, about the size of a normal sheet of paper, and 1/4 inch thick, in a heavy zip lock package... breaking the sheets up into pieces wasn't that bad, but I expect moisture was in the zip lock, before it was frozen, and this made the "easy open package worthless... both Mrs. with her finger nails, and I with my ham fists , could not get it open, I had to cut it open with a scissors, and put it in a different zip bag... these packaging people must never use their own products, I eat a lot of nuts, and they started coming in zip bags, and either you can't get them open in the 1st place, or you can't get them to seal afterwards... if I need to provide my own packaging, they could greatly reduce waste, by heat sealing their package and not having a worthless zipper added...
