Do you have ever play with Tenyo Nano Puzzle ?
I have some of them and it's very funny to built, I suggest you all try it at least once.
For a long time it was impossible to buy at a good price because the sellers on ebay selling them for over $ 70 !!! But I had always been intrigued by this metalic puzzle.

But I noticed that Hitomi now put them on ebay for regular prices around 15euros.

This is a chance to try and add them to your Tenyo collection.
There are many model, construction is sometimes not easy but the result is truly sublime. I like it.
Like the famous Tenyo Chouchou Butterfly or Jigazo Puzzle, all these kind of items are very clever and interesting.

Not sure who actually makes these but they are distribited by Fascinations here in the USA.
They seem to sell for about $7-$15 depending on the model.

Maybe Tenyo buy the right to sold them or the reverse.
I see on the website they sold art bank, micro bank, spin bank too.
Thank you for the information.
