Hi everyone!

I’ve just got my hands on this Homura Akemi nendoroid (I think 182?) secondhand for a pretty good deal! This is my first ever nendoroid, and I know she’s an older model so some issues are to be expected (especially slight stickiness, but she’s having a bath right now). However, I’ve noticed that while her right leg joint moves absolutely fine, her left leg joint is extremely stiff.

Does anybody know what to do in case of joint stiffness? The plastic of the joint seems to have integrity- it’s not sticky or warped or anything, and it’s getting a soak now in mild dish soap and warm water to hopefully soften it (along with the face plates). Does anybody have any advice on what else I can do to help with this joint problem? Thank you!
