Thus, the there is only one standard size (20cm in length) should be previously good measure that the chain fits. There is not a possibility to adjust the length. The rings are with me still all close together. Another reviewer reported that these can be pulled apart after a while of wearing or even arranging free, as it is seen to be seen on the product images.
The chain surface-coated so that it is non-allergenic. Allergic Reakationen have occurred so far.
The chain is closed bzw.geöffnet a magnetic closure. This works einwandfei in practice, you may only get stuck anywhere.
Conclusion: Beautiful fashion jewelry for women and something different than you can buy in the 0815 clothing stores.
