You know I am really keen on these twisted jump rings. You can use them to create a whole piece of jewellery or use one or a few jump rings to enhance other jewellery.
In my opinion, they are much better than ordinary jump rings because they do not mark so easily having only a very small edge that touches the pliers, they close together beautifully.
Because of their twisted design when closing you cannot see the join. They reflect the light so much and retain their plating because of less surface area touching the skin.
