High quality hard plastics, similar to GW stuff.
In case people don't know what the trick is, here is what I did (You will need tweezers/pliers, paper towel, two small-medium bowls, water):
WARNING: THIS INVOLVED BOILING HOT WATER. IF YOU ARE A CHILD, PARENTAL SUPERVISION IS ADVISED. IF YOU ARE A JADE FALCON, CONSULT YOUR NEAREST GHOST BEAR.
1) Boil water in a kettle (or microwave, but I prefer kettle)
2) Pour about 1-2" of boiling water into a small bowl
3) Get a 2nd bowl and add 1-2" of cold water (optional add ice)
4) holding the figure, place the part that is bent (or you want to bend) into the hot water for about 10-15s
5) Pull out, gently move to proper position (if it is too hot, or if needed, use pliers)
6) Repeat 4-5 as needed until it looks right.
7) Place figure in cold water, to cool down the hot parts.
This will lock in the plastic again after about 20 seconds.
For my wolverine, the hips had been pushed forward, so I heated the legs and hip, then moved it back, shifted the feet/ankle a bit, and using the pliers, adjusted the left knee outwards slightly.
This requires almost no pressure, it is highly malleable when doing this.
