Genius 24019 Power Seal closure system 6-piece set - really awesome

After I had around annoyed with the usual closures again, because the hinges are not really stable and broke partly upon the first application I tried Power-Seal. I have to acknowledge without envy, that the closure system is actually working well. Even liquids can be safely and leak-free "bagged". The simple but effective principle, see above, really awesome and virtually wear-free. Who the locks are too large, which can share easily and cleanly with a sharp knife and cut as desired. Can I recommend highly enough, unfortunately, I did not invent it themselves.
