I put a half a mug of water in the microwave for about a minute, popped my masked sculpt in the hot water for 15 seconds and it installed on the neck peg like butter.Got him last night. As others have said, really terrific figure. Quality rivals Hot Toys. Very stiff joints which is good. I used blu tac to hold the head in place. Really odd oversight. And the wrist pegs are also challenging to deal with. But minor quibbles. I need to spend more time futzing the jacket, pose, and scarf, but very very happy with him.
