I understand the safety issue of the seals...I remember the Tylenol scare back when I was a kid. I don't want cyanide in my food any more than the next person.

But why do some companies make them so annoyingly difficult to remove. Some of the good ones have a half piece in the middle to make it easy to pull up and off. Some, not quite as good, have a few notches around the sides you can work up to have "something" to pull with. But I hate the ones that have NOTHING to grab with, no notches to pull up.....you really have no choice (unless you have 2" nails or more) but to track down a sharp knife....just so you can open your bottle of ketchup or whatever.

Just a minor vent.
