Spacers are also referred to as stoppers. They make it possible for you to separate your beads and keep space between them. They are also referred to as stoppers or dividers, because they do just that. They stop your beads from clustering and divide them on your bracelet making it more balanced.
The Trollbeads spacers are made with a black rubber interior, giving them the ability to be placed at a specific spot on your bracelet – and to stay there. This way you can make several sections on your bracelet making it look balanced and have beads all around, even if you do not have a full bracelet yet. For bangles, the spacers can function as a lock since the spacers keep your beads from sliding off.
