Example Input: These are nice to have however, the edges are very sharp! I used these clips to put a new blanket binding around a baby quilt and when I slipped it off the blanket it sliced through the binding. I also cut my hand and a finger. I hade to sew a patch on the blanket binding.
Example Output: 4

Example Input: I like the price the most, but the packaging is horrible. They ball them up and wrap them so tight that the shape is lost. I should have taken a photo before I unwrapped it. I found out the best way to get them to take shape is to wet them and let them air dry.
Example Output:
