yoyo lipgloss

I haven't seen it in stores yet but there's a new lipgloss out called yoyo lipgloss. So what's different about it? it's on a retractable string that you can put on your hip, purse, bookbag, whatever you use. At first I was like why? but then i realized...wow i wouldn't lose it. I take a lipgloss in my clipboard with me at work. I'm thinking this would be a good idea.
