"I gave one of these kits to my 10 year old son to try out and he rates them "Awesome!" LOL It took him about 15 minutes to complete and I have to say, it really came out cute. It's easy to see that there are no missing pieces in any of the kits (which is sometimes a problem with OTC jewelry kits). He enjoyed making the first one so much he made another. My only recommendation for improvement would be a better fastening system. They just tie on. I suppose you could just use a small safety pin."
