This is a container of feta cheese, vacuum sealed to keep the cheese fresh. It works well. Really well.
But, actually getting to the cheese is a challenge. There's a pull-tab on the side that I
should be able to peel back to get to the cheese. But, to do that, I have to make sure my hands are really dry and the plastic is really dry, otherwise I can't get a good grip. Sometimes, the tab tears off without opening it. Yes, I can use a knife, and I often do if I can't tear the top sheet off. But, it's still annoying.
Once or twice, no kidding, I used pliers. Those work every time.
