Blue Plastic Tracks

Anyone recognize these containers and where they may have come from? Saw them in the background of this video... https://www.youtube.com/watch?v=XBMMYB0mLQY

These look similar:

They almost look Tin Type...are they yours or maybe know where they came from?

No they're not mine, here's a video....

and another.

I've had the full resources of the research department working on this. There's a chain of stores in Japan called Seria, they're 100yen shops, the equivalent of what I know in the UK as a pound shop. These containers are sold as by Seria as 'accessory cases'. This link is for a google search セリアのJRFコンテナ小物入れ
Enough!

Thank you very much Dr Chris. Looks like they are sold in 100yen shops in Japan similar to our Dollar Stores here in the States.  Can't get a fix on if they have a name or who made them to search further. They look really cool and the lids com off.
