Aluminum, so not as absolutely perfect as some higher quality metals, but the price! A real steal. It's the best thing going for this classic, very interesting top. It works just as good as any...

What's to say? It shows magnetic lines of force. Very interesting, fun and useful. I suggest getting this large version over the smaller one.

Case was much larger than I expected. Specs will rattle round inside without padding, but the gimmick works perfectly and will be a novel ise breaker at parties.

Great exploitation of a physical curiosity

The problem with this device as a gift is that it comes with a coin already inside, so it's hard for the recipient to understand what it's meant to do,without immediately unstapling the instructions....

Excellent and mystifying device.

Nicely crafted work, excellent for that price !

You can buy Klein Bottles somewhere else, but not this marvellous small piece of art. Really unique !

Perfectly dimensioned demonstration, does exactly what is expected from the description.

Does what it should, but the real gimmick are the two magnetic stripes with differently oriented field patterns ! I caught myself playing with these for quite a while...

Best puzzle of its kind I've seen yet (and I've seen a lot!).

Much too easy, but for small kids and that price, maybe worth. Definitely not a challenge for adults.

Stable hovering pen, the only small downside is that the tip is open and touches the acrylic frame, smearing ink on the contact point. Should have a small protecting cup there.

Nice model, worth the price !

As always, Hanyama cast puzzles never disappoint you ! These can just be ordered blindly.

Product is beautifully presented and looks to be of good quality. I am looking forward to giving this as a gift.

pour illustrer un cours sur les plastiques! désormais baptisée la baguette du scientifique :)

Great fun! Very decent music box and hole puncher to create your own melodies.

Not cheap, but necessary to make the most of the music box. Good quality paper.

Product is super-high quality. Awesome design. Just as depicted on the website and in the video. Would buy again.

Not as good as it has been - less good value this time.

Instructions are a bit complicated and it is more finicky than expected but result is pleasing.
