Ladies and gentlemen, please allow me to direct your attention to this quality emporium selling the finest closed, non-orientable, boundary-free manifolds sold anywhere in our three spatial dimensions.
An old-timey but delightful site written by a mathematician, and selling cool geeky stuff. I just bought a Klein Stein for my brother for his birthday. (One of the great things about hatrack is that it's searchable. If I link this here, not only can I share the fun with all of you, but I can actually find it again when I want to look for it.)

He's got a version that zippers apart into two opposite-twist Mobius strips. Did you see that one? It's elegant and beautiful. Every well-dressed topologist needs one.

quote: CLEANING SUGGESTION: For tough marks on the "inside" (which, of course, is the same as the "outside"), use a pair of small flat rare-earth magnets, each wrapped with soft velcro or cotton, and wet with Windex.
Keeping one magnet on the "outside" (which, of course is the same as the "inside") and one on the "inside" (which, of course is the same as the "outside"), you can scrub both sides of the glass at once. Since both sides are really the same side, so you're really scrubbing two sections of the same side -- a nice labor-saving method that also works on Moebius Loop Conveyor Belts.
