Product Name: Klein Bottle 4D
The Klein bottle is a geometrical object, named after the German mathematician Felix Klein. He described it in 1882, and named it Klein’sche Fläche (Klein surface).
Because the surface is non-orientable, there is no “inside” or “outside”. This means that if a liquid were filled “in the bottle”, it would run down its surface.

Excellent quality, came a little less than a month, oochen well packed in several layers of foam
I went to Moscow whole. Packed perfectly: thick tightly fitted foam outside the branded box, then tight the box itself with the goods, inside it is also very tightly fitted.
It was safe and sound, although the packaging was quite crumpled. Two layers of foam Foam work miracles. Reliable store, I am pleased.
All goods. Very fast delivery!
This is exactly what I wanted. The workmanship is perfect, it is a very beautiful item. The price is also very attractive. I have always dreamed of having such an item, thanks!
As expected, a Klein bottle of about 16.5 cm arrived. I ordered from Japan and arrived in 6 days, half a month earlier than planned. Although it is an inexpensive product, it is strictly packed in Styrofoam, and I can see that it is shipped very carefully. I am very satisfied. Thank you very much.
