The only thing that I have here at "fault" is that in this type closure clip only the choice between 6 pieces and then equal to 30 units, which is now but not as critical - only to me personally that was not enough, and wants not rely on the same 2 packs, because then I'd already priced in the order of 30 Pack was and that's way too much. And I knew in my initial purchase of these things is not how good they really are. Also that these clips are pretty big / long bothered me - I'm a 1Personen budget and did not know what the probably going a bunch of huge bags in which I handle animals with soups etc.. For me it's about relatively small packs (flour, ground coffee and the like), but the clips are too long. But you can make do so, for, as the clips yes consist of a tube and a U-shaped clamping rail (all plastic), one can prima share and make a long clip 2 or even 3 small with a sharp, strong knife and the functionality remains completely preserved and has so with the first 6 pieces then equal to 10 or more, as I wanted ;-) This goes with the classic clips with hinge course not, that are even often too small and have systemic just 2 mounting points left and right, which ensure that, depending on the package thickness in the middle just bulges the clip and is so rare tightly and correctly closes - that's just better at this clip, because from start to finish everything is clamped evenly.
