Enables easy threading (basically, does what it says in the name!).
I get a lot of people asking what the best needle threader is; and it is this one. Yes, really. I know, it's the same as the thing your Grandma/Aunt/Home Ec Teacher had in their ancient sewing box. That's because it works really really well.
Caution: Do not pull the Needle Threader with force, it may damage the threader. They aren't kidding with this. These threaders are the best at threading, but they are still just thin aluminum and stainless steel wire. They do break if you pull to hard, so treat it gently.
