Black nylon plastic with a matte finish and slight grainy feel.
About this Product
Here is my first knuckle ring which I have just received. I am surprised because it looks very good, and it is flexible therefore not easy to crack (I have it printed in 'black strong & flexible). I am sure metals will be also nice.
14mm inner diameter, suitable for upper part of finger.
Feel free to ask any questions or requests. Regards.
