Handmade Glass Klein Bottle

I've been looking for a klein bottle for awhile now, but they're hard to find. This guy makes them by hand, though they don't look hand-made - the one I got was basically flawless and I was expecting it to have a bit of a rough appearance as a result. But there's no hint of a blem anywhere on it, it looks amazing! It's also a bit "bigger in real life", as I was worried it'd be tiny but it's got a good size to it. Packing was excellent, it was wrapped in foam sheet, wrapped in small bubble wrap, wrapped in large bubble wrap, in a sturdy little box. The base was a good compromise between having all curved edges and needing a somewhat flat bottom. I really don't think I could have asked for a better specimen. (the glass has a beautiful polish to it and the seams are just flawless) It's great for anyone looking for "math art", or a classy gift for a nerd of any description.

Cliff & Co. made me laugh more than I have in several years. Putting aside the high-quality workmanship of the bottle itself, the paperwork that comes with it is worth every penny, and is sure to brighten your day. Thank you, Cliff! Buy this bottle — You won’t regret it!

Beautifully made.

If you don't know what a Klein Bottle is maybe this isn't for you, but if you are a fan of this fascinating mathematical object you can't do better than to get one of these. The shape is beautiful, the glass is high quality and the craftsmanship is superb. The bottle also came in interior packaging decorated with little hand drawn sketches and comments about the object inside. I'm keeping that.

Fantastic present for my mathematically obsessed 12 year old son. The care Cliff places into the shipping, instructions, and craft is immediately apparent and the whole family enjoyed exploring the bottle. I highly recommend for anyone looking for a gift for someone who enjoys mathematics.

I always wanted the novelty of owning a 2-dimensional object. The ACME Klien bottle absolutely delivered. The bottle is actually gracefully pretty. This is an outstanding example of hand-blown glass. While the item itself is worth the money, there is the added bonus of several pages of clever and humorous documentation that comes with it. Even the shipping box was a surprise as the shipper decorated the box with hand-drawn illustrations which also appear on the bill of sale. If you have an educated person (or not) in mind who might like a Klein bottle buy it and, just wrap the whole thing up when it arrives leaving it in the shipping box. The bottle is great and the personal touch out of this world (literally.)

I am so glad I found this particular Klein Bottle. The object itself is solid, well made and pleasing to look at. What I found most enjoyable and surprising was all the fun literature the supplier included. He clearly enjoys math, physics and as important, fun. Even the box it came it had hand made drawings on it that were both informative and amusing - we took pictures before recycling it. Oh, and it came with relevant stickers - who could ask for more? Thanks for making this such a delightful purchase!

The detail they put into the whole package is incredible. From the box to the receipt, it's clear they put a lot of love and effort into delivering a quality piece.
