The miniatures are pretty nice, they are simple to assemble, as the individual pieces have specific slotting system, so it's easy to figure out what pieces go where. This is actually pretty important, since there's no assembly handbook. The dragon is a sculptural piece and definitely needs adult assembly. I had to use clamps to hold the legs to the stand while the glue dried, I needed more hands to be able to use the insta set on the dragon, so the clamps were an easier solution.
Note: This is not a snap-tite kit, while some pieces fit wonderfully, most need to be glued. So parental assistance it needed, in addition experience with miniatures will definitely help.
