The Steel Basicline® Feather clamping ball ring has a ring thickness of 1.2 mm. The ring has a diameter of 10.0 mm. It has a 925 sterling silver element in the shape of a feather as a clasp. It is a great alternative to our Labrets, especially with the pendant. Like all basics of the Steel Basicline®, the jewellery can be sterilised in an autoclave and is absolutely safe for allergy sufferers because the material is kind to the skin.
