... from your Zero Volume Klein bottle distributor September 12, 2021 -- Just received a shipment of glass Klein bottles.  They're beauties - outstanding glasswork.  Borosilicate artistry!  My not-entirely-reliable robot has moved the boxes under my house, and they're now available for sale.
Very Big Klein bottles $600 to $6000
FLYING THROUGH SAN FRANCISCO?  Don't miss the exhibit at SFO  -- "Mathematics: Vintage and Modern".  Mathematical art by Lucas Clarke, Chris Hamann, Scott Kim, Henry Segerman, Carlo Sequin, Stacy Speyer, Kokichi Sugihara, and Xing Wei. Glass knots, old calculators, cool Rubik's cubes, oddball crypto machines, and, yep, Klein bottles.  All at SFO, Terminal 2, until May 2022
(As of 2021 mid-September, several countries are unreachable by airmail post: Australia (!), South Africa, Philippines, India and all of South America )
