They were too small for my application but will come in handy

So, at first I was all set to return these. They seemed too small for the masks I bought from Stark's. I've never used cord locks before and had no clue what I was doing. Then, I saw a review saying that they used a paperclip to thread the ear loops through the cord lock. Well, I didn't have paperclips, but I did have bobby pins! It took some effort, but for anyone else who is not in any way crafty, here's what I did: 1. Threaded the bobby pin onto the ear loop 2. Pressed the cord lock in and stuck the bobby pin through it. At this point, the ear loop still won't go through. 3. Used my teeth (you could also use a grippy tool like pliers, but I was working with what I had) to pull the rest of the ear loop through. And now the mask fits perfectly!

I use these on drawstring pants for someone who can't tie them. Its a life saver. The only downside is that for the thicker strings I need to cut off the hard end, and use a paper clip to pull it through. Then I tie a knot. The hole for the string would fit about a normal shoelace end with some wiggling. Note that I bought a second box and some of them had a hard metal piece sticking out of the side. Clearly a bad batch. About 6 in the box were unusable. Some of the others had a bump - but not one that would hurt someone.

Great
