Clothespins get used up around here and some faster than others. The good ones last for years. The cheap Chinaland ones from the bargain store are undersized, have inferior springs and come apart at the slightest provocation.
Then there are the bags that need help staying closed. Sometime between my youth and now the material these bags are made of became made of memory stuff. They cannot be wadded up, twisted up or folded closed and stay the way. They instantly try to go back to the original shape. They ought to make cars out of this stuff. Twist ties are a pain in the ass and I take them off and put them in a safe place in case I someday will need them (they are good for bundling wires behind the computer). I do not buy the clamps that are sold to close potato chip bags as they are a solution for a problem I do not have. I have clothespins although those other clamps work better.
I even have used clothespins to hang clothes (in the Navy we used lengths of cotton cord) on the rare occasion that it was not raining, the air had more air in it than dirt and/or the wind was not blowing a gale. We also have a birdshit problem.
While I'm at it I might as well discuss plastic bags (ziplocs and such). Why buy plastic bags when your cereal and your bread comes in them. If you think they are contaminated because they had food in them then you have a problem I cannot address so you might as well not read any further. These cereal bags keep the chips, cookies and cheese in the fridge better than any plastic bag. The bags your vegetables come in are designed to pass gas (pardon the expression) so they do not keep anything very well. The bags the veggies come in from California also are made to pass a certain amount of different gases so the the 14 day old produce you are buying can be sold to you as fresh. I drove a produce truck and believe me they ain't fresh.
I do not use plastic bags much. Mostly I use left over glass jars that I emptied the product from myself.
