When I am not sure what to put on or need to grab something before running out of the front door this is my go to necklace. My mum got this necklace many moons ago, it was from M&S and cost a couple of pounds. It has lasted a long time and whenever I wear this it always gets compliments, it causes a lot of interest as people always want to know if I keep anything in the small envelope. I must admit that I do not, I once put a few pounds inside it but decided it was not the safest place for them.
Maybe I am over cautious.
