These clothespins seem to me to be as sturdy as old timey ones, but I seriously doubt one can hold 10 pounds. Figure a quart of water weighs about 2lbs. I think there is a translation problem. Plus, if there is a breeze, one pin could not hold that much. Perhaps they mean the spring is coiled at that rate. I don't know. Nevertheless, these pins hold well enough. They are not "craft" weight, they are utility weight. And, why not use more pins for garments? What is the point of skimping? These are tools. I now have 100 pins. I use 6 to hold up 1 pair of wet jeans by the waist--no folding over the band, either. This holds in a fair breeze. If the breeze is a little stronger, I fold the jeans over the line where the legs met the seat, and clip from the sides of the legs to the seat. One doesnt' have to just pin to the clotheslines. I use the clothespins that way too for garments I drape on a wooden rack. Pinning under the armpit at the side seam so no or few drying "dents" are made by the jaws of the pins. For delicates, I use a thin cotton hanky and pin over that. The pack of 50 have some poor quality, which used to be called "seconds". Those are rough, not completely sanded. But, they hold, and they will do fine on denim, I just wont use them on snaggable garments. Plenty are sanded enough. There is 1 American company making beautiful clothespins. 16 pins which works out to max 8 garments for $25 plus shipping. They look lovely, but for day to day, I'll just use more pins strategically placed. If the pins splay sideways, turn them upside down, to open. The coils tend to be more flexible one way than the other even in the old times. I started helping Mum hang out the wash when I was 6. Couldn't even reach the line at first, just shook out and handed. I never liked the way she folded the top edges of garments over the line and jammed on the clips. Dried out with dents and bunching. That's the old technique with the split pegs, from the same era of constant ironing. The way I do it, no ironing needed. The clothesline bags appear to run about $25 average, so I used some scrap fabric, sewed a square bag by hand with a gathering seam, put a strand of kitchen twine though, and presto, clothes pin bag with daisies and bees for next to nothing. I I use clothes pins to hang it just from the line, or from a plastic coat hanger to move along. It's good to take in the pins when dewy or raining so they don't mildew. If they get soaked, I just leave them on a towel to dry before bagging them. Think of wooden spoons. When folks buy a box of nails, they don't worry about dropped, crooked or dull ones, they get enough on hand to do the job with some left over. So go ahead, treat yourself to extra clothes pins at this rate. I took a star off because of the seconds mixed in with the better made.
