They run about $6.50 a piece. I get them off ebay from Zira28 in Japan. They get here typically in about three days.
Here are my work in progress pictures for Ysanna Isard. She is not in her imperial outfit but in that sexy commando outfit. As you can see for the torso, I'm using a green waterballoon. I cut both the top and bottom on the balloon and stretched it over the body. I used a tiny dot of krazy glue to hold in in place below the neck and groin. The excess latex was cutoff and the back seam is glued in place. This hides the joints on the torso but still allows for complete movement.
For the legs, I used just the neck of the balloon cut off at both ends. Then I secured it and stretched it to fit. The arms could be covered with a balloon that clowns use for making balloon animals. Its just the right size to fit over the arms and be snug.
This technique is great if your going to make any Marvel Superheros using the Microman body. All of the detail of the body shows thru the balloon and its skin tight.
