I use the sealing of plastic bags etc .: Gewürzbriefchen, vermicelli, pickled cabbage in half kilo sack, mozzarella, etc. For the terminals are ideal, and the downright wasteful number in two sizes, I'll always have one at hand. Certainly seems to me not in the freezer: what for? But there's soft wire caps to trashing that also usually are still in freezer bags.
I use something like this for years, but at the price I have not yet seen. Moreover, the terminals come in a sturdy storage box, so that does not have herumpurzeln in a drawer somewhere.
