Our brass bangles are open to fit most wrist sizes or expand to fit the forearm as an arm cuff. The brass is made only from pure copper and zinc metals, both of which are highly conductive and said to promote better circulation in the body. This can help to reduce pain such as rheumatism and arthritis.
Copper and zinc both oxidise in the air and water, so you may experience some green (from the copper) or black (from the zinc) marking when wearing brass, particularly if your skin is moist. This is perfectly natural and the marks easily wash off. Some people choose to coat the brass with vaseline to avoid marks, but by doing so you do not get the therapeutic benefits from wearing these natural elements.
