These bracelets are custom made for Rockin Beads with a 3.1mm slide on end. With so many different size beads and hole sizes and so many different styles of chains almost all of us have ended up with beads that we love but just don't fit. Rockin Beads has been working with one of the factory to get one that will and here it is. Our new Faux Euro chain is Silver plated brass with only one end that detaches to add beads. The end was specially made with no thick parts that beads will not slide over. This chain will accommodate beads with a 3.5mm hole or bigger.
