Test 1: Failure. The DZ hands were too short and fat, like little child hands. Plus the resin didn't match, but I was planning on blushing that out.
Test 2: Another fail. The Resinsoul hands were not a match; they're exactly the same length and overall shape as the Miro hands AND the wrist-ball thing is too big for the slender Miro forearm/wrist connection. So the hand sits on top of the forearm piece and... well, it would work if you wanted your doll to have a swollen deformed wrist look going on. HA!
Also, the myriad of s-hooks I had didn't fit in the Mirodoll wrist either. The forearm was so small they were using what I thought was YoSD sized elastic and the channels were too small for s-hooks to fit. I tried several hooks but none of them worked, they all kept getting caught on the resin, scratching it up and unhooking from the wrist.
So, if you were planning on replacing your MSD Miro hands with a prettier pair of MSD hands I wish you the best of luck finding something that will work.
