Carbon Cube Metal Density Cubes Pure Metal High Density Element Cube for Element Collections Lab Experiment Periodic Table Collection DIY Teacher Science Creative Gift（Carbon，1 Inch）

Comes with an acrylic casing. High quality, and a neat desk piece. Titanium is a fraction of the density of Tungsten at a fraction of the cost so it's a nice beginners collectible.

This is a unique way to illustrate how various metals look and feel. It is a great educational tool.

Came exactly as described. Very happy with purchase.

It's shocking how much you can learn by feeling these, seeing the color shades, feeling heat conductivity! I wish all the common metals were available though. If they had all the affordable transition metals I would like them so much more.

A nice novelty item that appears to be exactly described. I ordered several from this company and it's interesting to feel the different weights due to density differences.

It doesn’t actually DO anything but it’s a nice addition to my element cube set. It’s attractive, clearly labeled and very smooth to the touch and makes a great desk toy.

Metal block is as described, but instead of the nice clear storage case that it usually comes in this one came in an oversized opaque container that is only fit to be tossed in a drawer.

extraordinary piece

This is lovely, great cube. However the packaging was awful. The writing had transferred to the little box and it was just loose in a Jiffy bag. You’d expect a bit more for the price
