One PAIR of medium size aluminium sling rings. Make your own ring sling or use the rings with a short wrap as a "no sew ring sling" or for fancy finishes! Medium aluminium sling rings are great for your own ring sling projects - specially for thin fabrics like silk. The outer diameter is about 7,5 cm. The rings can be washed in a machine but we advise you to cover them with a sock or piece of cloth to protect the color.
