Since I found out my Obitsu 60 from 2006 is melting, totally on me and how I've treated him last year wasn't good for any of us, I decided to check the others I got around the same time.
The rooted 1/6 scale heads are getting a little bit sticky. Not wet but I could feel a little something on my finger. I don't really touch their heads much. The larger soft bust seemed to be okay. Hopefully they'll be fine, there have been old sticky Barbies forever. Might give them a talcum powder dusting later. The Volks from the same era I checked are okay.
