The discs are available in 5 mm and 6 mm, the thread is fitting for stems of 1.6mm thickness. Can be sterilized in an autoclave and are absolutely harmless for allergy sufferers because of the skin-friendliness of the material.
Titan Basicline® is completely nickel-free and is suitable for sensitive and very allergic people. It is half as heavy as steel. It is not really the titanium itself that is so good for the body but the layer of titanium oxide that forms on the surface. The oxide layer also acts as a barrier against other substances in the titanium leaking into the body. If the titanium oxide surface is worn away, a new layer is formed immediately.
Titan Basicline® is a slightly cheaper alternative to Titan Highline® as it does not have the same high-gloss finish and can be experienced as darker in color.
