Brass Plated Pin Back: 1 Inch

I was excited when I found these on my PC, and even more excited with the price. I had plans of purchasing more! But, I was very disappointed; my finger nails broke, and, my fingers were so sore, trying to open the pins. The pins locking spring were so tight, I could not open them. I only opened one of the two bags, because I gave the other bag away. About 20, or, more of the pins would not open. I will be returning them to my local store. Too bad, about the other bag of pins I gave away; because I would return both bags.
