The 1.5-inch Tungsten Cube is machined from a single billet of 99.95% pure tungsten and finished by hand to a precision brushed surface that catches light differently at every angle.

Pick it up and your brain misreads the information it is receiving. Objects this size are not supposed to weigh this much. Set it down and it stays put. It does not slide. It does not tip. It simply exists, machined to tight tolerances, and will outlast everything else on your desk by centuries.

Tungsten is extraordinarily difficult to machine. Its hardness and its 3,422°C melting point demand specialised tooling and feed rates slow enough to destroy standard carbide cutters. The cube you receive is the product of industrial precision machining that most metals simply cannot tolerate.

It has no practical use on a desk. That is the point. It exists to demonstrate one of the most remarkable properties in the physical world: that something this small can have this much mass.

  • 5 out of 5Just. Do. It.

    I had this majestical block in my cart for nearly a year before I decided to buy it, I am sad I waited so long. This cube has changed my life, I wake up in the morning with joy seeing it on my desk. This cube is the thing you need to fill your empty soul. buy one.

  • 5 out of 5Denser than I expected

    Came quickly and well packaged! I knew tungsten would be dense but I was still surprised by how heavy a small cube could be!

  • 5 out of 5It's a cube and it's pretty cool

    I mean, I got this for my boyfriend. It's heavy. Makes your palm feel good. Small and heavy little cube. I didn't understand wanting these metal shapes till my bf asked me for a copper ball. Idk how why he wanted it so bad but I bought it.. and I understood. Few months later I bought him this little cube. Something about metal shapes that are heavier than they look just.. makes you feel alive. Get the cube. Live a little

    Giving this as a gift. It was SOLID and surprisingly heavy. Seems like a fun gift to give someone who has everything

  • 1 out of 5Nearly a month in transit

    The cube itself is fine and matches the description. But it sat in transit for almost four weeks with no tracking updates, and it took three days to get an answer from support. Product is good, the shipping experience was not.

  • 5 out of 5Heavy enough to cause existential angst

    Heavy as described. My son of 1.5 years old could not lift it which was my goal. He totally lost interest in about 10 seconds though so that's a bummer. I like to hold it now while watching tv. I'll let its heaviness comfort me. But it sometimes makes me think about how everything is made of atoms, even myself. So sometimes it also gives me some existential angst. Would definitely recommend though.

  • 5 out of 5My coworkers will not leave it alone

    Brought it into the office for a week as a joke and now it lives on the shared desk. Somebody hides it, somebody finds it, the whole team is weirdly attached to it at this point. Buy one for yourself and a spare for whoever steals it.
