Just an alert to anyone who hadn't already encountered it - the iridescent bronze plastic that makes up Chewbacca's upper arms and legs is prone to cracking and breakage, aka the dreaded Gold Plastic Syndrome or GPS. I've encountered this on 2 instances of this toy, notably on the upper arms.

If you own this toy, then it's probably best to leave it in the mode in which you prefer it and refrain from repeated transformations.
