## Customer Reviews

### ⭐⭐ 2.0 out of 5 stars







  
  
    Not for average toy customs, too expensive!
  

*by N***N on Reviewed in the United States on September 6, 2021*

I got this hoping it would be good for modifying 5-poa figures for more articulation. The plastic is very soft and while the ball and sockets to fit, they resist superglue onto other plastics. Superglue does not work on these. Flimsy and they don't hold poses, hardly any friction between ball and sockets. WAY too expensive for what it is. I don't know if these parts are meant for a particular model. I am not happy with these, but they do fit together, else I would have 1-starred it.

HGのガンダムタイプのほとんどがクビが短いと感じてしまうので、ガンダムタイプを作りこみたい時にコレのボール軸を必ず使います。キット付属のダブルボールポリ部品を使わずコレにしてしまうと二重可動は出来なくなりますのであまり他人にはオススメしませんが俺には必須アイテムなのです。
