Gorgeous cuff links

I saw these cuff links last weekend when shopping with a friend. At first I thought they were bowls full of beads. Upon closer inspection I realised they were cufflinks. Two chinese knot balls joined with a piece of elastic. They were so gorgeous I couldn't help but photograph them, and also play with handfuls of them until the shop assistant told me off. There were ten bowls of all different colours, I'd only photographed four of the bowls before being asked to stop.
