This is a new piece of jewellery that I actually bought months ago. Maybe even a year now. It’s been sat in my little jewellery tin for all that time because when I first got it I was unable to undo the balls on the bar to put it on. I’d gone back to it several times and never been able to do it. I was debating getting some small pliers to it but I’d never got round to it. But somehow time has done the trick. And when I went into my tin this week looking for jewellery I tried this one again and the balls came off easy !
