We got this set and it was very beautiful. The Mask and Arm covers seem well enough constructed, and they both fit well. I'm afraid the elastic may snap off the mask if my daughter isn't too careful with it though, since it was gotten for her costume.
The Necklaces is made with materials that are appropriate to the pricing, but it also means that pies easily pulled or fell off. We were able to fix it for the year for us with some hot glue and my jewelry tools. Overall they were very simple fixes, but the chain coming apart is harder to deal with if you don't have the jewelry pliers on hand.
