I often hold the ass to move the waist. Finally, I found those area were faded. I did not mean the red colour. I mean the shining. So call "die cast"! Must worse than pink underwear plastic version. Faded shining, peel off......
Thanks for your help
also, i want to change to use MK42 tony stack arms. Should this part of hot toys body front arms be taken off but i feel too tired?
