Each is held on with a chunk of blue tac and an industrial staple. They become easier to hold. Also I don't drop or knock them. With metal miniatures they do become top heavy. That's why the generals, characters always get a scotch cork with the wood piece on the bottom. Those below are BTD and are metal. To keep them up right when not in my hand they rest in a solo cup 3/4s full of BBs.
Also I primed up the last BTD Auxilia dudes.
