Half-persian 4 in 1, with ring and carabiner. Made out of polished stainless steel. It's very strong, doesn't rust and it's comfortable to wear.
Measure the lower part of your neck. Keep in mind that the necklace should be a bit loose on your neck and not too tight, so select the closest option to your neck size plus a few centimetres.
On the picture I'm wearing a 38,5cm long necklace. The lower part of my neck is 34cm
