I bought this pack to give the rings as gifts. I've had the rings for a week now and the one pictured I have worn non stop since! I think this pack had a good variety. I gifted these rings to ages ranging 10-65.I'm so impressed. I was worried because the price does not reflect quality stainless steel, however I have been nothing but happy and can't wait to hear feed back from the gift recievers!!I'm not metal expert, but they are true stainless steel from what I can tell. There are scratches on the ring, but nothing significant and no coloring under them.The only thing to note is they adjustable. The signs are adjustable, however I found it impossible to bend the ring. Some sort of tool or pliers will be needed to adjust the rings. I don't think that is a bad thing though, just keep it in mind.Packaging was nothing special, just individual clear plastic bags. Something else to keep in mind when ordering.
