As described by clients that are forming sharp edges. Also is wrong in my opinion the first photo match the delivered product. In the first picture can be seen that there is a flat wire (I have such a high-quality rings) but from the product is round wire, thus cheaper to produce. I am not satisfied with the quality and if I do not look completely wrong, not the product pictured. On the following photos the round wires are then to recognize when you look closely. I'll look around for better.
