The slightly bended bar is externally threaded. By the way, all of the threads in our jewellery collection are standardised, so that you can combine rings, bars and attachments! The suitable replacement balls can be found among Attachments section!
The article can, like all basics, be sterilised in an autoclave and due to the skin friendliness of the material it is absolutely harmless to allergic persons.
Attention: the stones are not socketed but glued. They can get lost depending on the way of use. You should not wear an article with glued stones in swimming pools, baths, saunas or similar conditioned surroundings. Please do not lay them into cleansers or germicides.
