Tungsten Cube Metal Density Cubes Pure Metal High Density Element Cube for Element Collections Lab Experiment Material Hobbies Heavy Small Objects Experience (Zinc, 1 Inch)

This little cube is very cool and funny. A little sharp around the edges, but has a heart of gold, figuratively speaking. In reality it has a heart of copper, which isn’t bad 🛁. Copper’s very conductive, so I’m sure there’s a metaphor somewhere in there.

The accuracy to which the cube is machined is perfect. Right on the dot at 1.500 inches, maybe 0.0001 - 0.0002 inches oversized. At this resolution, simply holding the cube in your hand for a few minutes and warming it up will change the dimensions. Weight is 1062 grams on my kitchen scale. Obviously my kitchen scale doesn't have a NIST-traceable calibration, and I don't mind that it's slightly overweight. The flimsy, thin plastic storage box that it came in was completely destroyed in shipping. Dear manufacturer / seller: if you're reading this, please include a much sturdier box, or none at all. It's simply a waste of resources (i.e. my money) to use the one you currently do. The price... Well, it's certainly much cheaper than some other identical offerings here on Amazon, and I looked thoroughly, both here and off-site. This was the best deal I could get, but I still have buyer's remorse. It's a lot of money for a cube that sits on your desk and does nothing, especially considering the bulk price of tungsten is about $30/kg.

Pretty cool

Great finish. Good looking specimen. Thank you.

I love these cubes.
