>>5384812If the joint comes apart in the middle, put tissue inbetween it, clasp them back together, then tear out any tissue that juts out. This is more of a stopgap measure.
If you want better results, look for a transparent nail polish, coat the middle part of the joint, put it back together, then move it around as it dry a bit.
People suggest super glue, the catch being that, you have to instantly keep moving it until the glue settles and hardens, so that the material build up to provide extra friction is there, but the super glue itself doesn't bind the joint together but I've never dared try it, since the joints used for the skeletons are uniquely colored.
I personally have never tightened the joints on mine, just am more conscious with balancing its lower spine and hip.
that aside, I love the rust edition... I ended up getting it because I can't find any of the bone colored ones in physical stores. The texture and wash on this is a lot more convincing than the Kirin in some ways.
