hey mate! unfortunately, I don't know of how to get them for you at this point. I got these when they were released and I just ordered them through a toy shop that is run by my buddy and actually has someone on the ground in Japan to get all Jap released goodies.

The catch is that someone has to be physically in Singapore to collect them when they arrive if not he rarely holds them for more than 2 weeks before releasing them on retail again in his shop. I usually have my mum or brother collect these stuff for me but the thing is that whilst I know they are there and I have them, I don't see them at all till I go back to Singapore for a visit.
