Seibu 9000 L train (limited)

Can anyone tell me more about this train?
It seems like it's a special one?
Very attractive, with nice detailing...I like it a lot!

[Super]

I agree as the train is attractive. The only thing I know is that it was released in late December 2017 and was a special release not retail. The Logo is for the Saitama Seibu Lions Baseball team in Japan. I am not sure why this is so special but maybe the baseball team celebrated some kind of milestone and contracted Plarail for a train...maybe? Maybe it was only sold at the stadium but this is all speculation on my part. We mentioned it here but no information. https://www.blueplastictracks.com/showth...seibu+9000
