I suggest you may press the wire towards the body a little bit at the position of the third button. The wire is just too straight and make the third button look like being opened
kato i actually can't! ..the wire inside the coat seems to start halfway down his chest so it's very difficult to get the top of the wire to lay flat, i can also feel the pointy tip of the wire trough the coat and this worries me!
..sorry i don't like to be complaining but these things really bug me, especially on a $600 figure!
You can clearly see the top of the wire in these pics, i'm not sure it that's where you intended it to end Kato but i find it very difficult to keep the coat naturally closed this way.
