    Really like it!
    Got it as a gift in "Silver-mirror." I like this polished look more than the one on the product page. Feels solid, fun to look at. Wife really digs it too.

    One issue - the fastening hook on the cord is open a little too much; looks a little insecure. Just like a previous customer said - may want to use a different cord.

    These are exactly as I'd hoped.

    Good shipping time and great packaging! I've received larger 3D printed objects for cheaper, so I'm still trying to figure out if it's WORTH the price, but the vendor was very responsive and nice, so FULL POINTS for that. They also threw in a little gift, which I super appreciated. It make me really happy :) And these certainly work and roll between two flat surfaces smoothly! The math and science nerd side of me keeps poking its head up through the strongly arts and language ocean whenever I look at these :D

    This cuff goes with everything. It is exactly what I was looking for. I love the details and the artistic design. It feels really solid. I can see it is great for women and men, which is very hard to find in jewelry.

    Got this for a friend as a gift, and she's totally in love with it! It's even more polished and bright in person!

    I love everything about it. The quality is even better than the photo shows it to be. I'm definitely wearing a piece of art.

    Love it. I think it arrived earlier than the estimate, too, which is awesome. The packaging was a nice surprise, especially the card that speaks about the Umbilic Torus.

    As for the cord, I ended up using my own. The clasp looked odd to me, so I just switched it out for an old one that had a more natural look. Regardless, the actual pendant is awesome. I chose steel with a bronze coat and I love how it turned out.

Curious designs inspired by a curious universe.

The universe is full of mysteries. Where do we come from? Why are we here? We may never know the answer to all of the questions that are out there. But if you open your eyes and your mind you'll discover that there are hints everywhere. Secret patterns in the foundations of our reality, written in the ancient languages of science and mathematics, that permeate every aspect of our lives.

Illogical is a shop dedicated to those hints. These products serve as reminders of the infinite discoveries that lay all around us. They pay tribute to the never-ending quest to reveal the fundamental truths of our existence. And through this focus on logic and intrigue a unique style emerges, one that captures curiosity and fuels creativity.

All items are custom made using advanced 3D printing technologies.

Note: I also host my personal maker shop on Etsy. You can find that at
