If your Klein Bottle arrives broken, call or send email and we will immediately send a replacement. We slightly guarantee your Klein Bottle for THREE MONTHS against any cracks or breakage, whether due to earthquakes, clumsy undergrads, or greasy fingers.

If you discover one, contact us immediately and we will refund your purchase price right after you receive the Nobel Prize. Furthermore, we guarantee for TEN YEARS that any polyhedron spanning your unbroken Acme Klein Bottle will have about as many edges as the sum of its vertices plus faces. We further warrant for ONE MILLION YEARS that within a Euclidean plane, the square of a right triangle's hypotenuse will equal the sum of the squares of the two remaining legs.
Can't you break this with Lorentz contraction; it seems that would be equivalent to non-Euclidean geometry but legally within the terms. It's all about frames of reference I imagine. Though my inclination is that it might hinge on the meaning of "within" used.
And he's funny. Mostly. ;-)
This was really fascinating read for a young nerd around very early 1990's.
From http://www.kleinbottle.com/drinking_mug_klein_bottle.htm :
"The 7 mm air space separates the inside from the outside, so ice water won't cause condensation. This extends the life of hot or cold drinks, saves energy, and helps stave off the dreaded local thermodynamic equilibrium."
But seriously just read the whole page, this is like a bear hug from a friend I didn't knew I had.
Reading any page is a joy.

You could probably put a carbonated drink on it, though...
yes it does, you just pour in/out from the bottom.
That's basically the whole novelty of a Klein Bottle https://en.wikipedia.org/wiki/Klein_bottle
Would it be more correct to say that there is no inside surface? And it was just a pun that went over my head?
[edit]
As my friends (online and off) can attest, I make Klein bottles mainly for fun. It's a zero-volume home business, small enough to be run from one room; the warehouse occupies the crawlspace under our house.
Of course, the best part of Acme Klein Bottles is meeting people: via email, occasional visits, talks at schools & math colloquia, and chattering about physics & LTE & coding with friends at my day-job (Hi Newfield People!). Which is to say, it'll be a while before I recast my kleinbottle website - I'm having too much fun doing other things. -- from an earlier post
