I thought these were a bargain until I received them and saw that the size had a lot to do with the cost, they are teeny tiny bead stoppers which you can move around the bracelet easily and secure at either end of the beads, when you fix the stoppers in place, they stay there until you wear the bracelet and start going about your daily life...then the stoppers realise the weight of your other beads which make them all become loose. Cute for a short while or great to anxiously play with as you move your beads around your bracelet when talking..
