The Handmade Glass Klein Bottle was $94 when we checked it on 2026-10-01. That observation is 11 days behind our latest weekly run, so we are treating it as an estimate until the next check.
This elegantly curved glass Klein bottle will intrigue and delight any mathematician, physicist, or science buff. Like a Möbius strip, this Klein bottle has only one side. In addition, a Klein bottle has no edge - the connection from "inside" to "outside" is smooth, and the bottle has no lip. To a mathematician, this is zero-volume because it doesn't divide the universe into two parts. Despite this mathematical property, it's possible to fill it with water, although I don't recommend it, since it's difficult to dry (you can't get a cloth "inside") Each Klein bottle is hand blown from clear glass, so the exact shape and dimensions may vary slightly. Along with the glass Klein bottle, I include entertaining and (possibly) educational documentation, and a removable calibration decal.
Editor's note
A bottle with no inside that is also microwave safe is the funniest sentence in this whole catalog. The math nerd in your life needs one.
