Tin Cube - Metal Element Cubes - Laser Engraved Density Cube Set for a Periodic Table of Elements Collection - (Tin, 1 inch)

It's a nice cube but I had to return the first one because Indium is a very soft metal and the packaging wasn't adequate to keep the first on from being crushed before I received it. The replacement is fine because it came in a box as opposed to a sack.

These cubes are really great, easily learn the differing weights of the elements however the cubes are very, very small. Will not work for students in a classroom as they will easily be lost. Think 1/8 inch square, a bit bigger, but for a high school student or adult they are really cool.

This Copper cube is really neat

Ordered mostly for the Tungsten cube and I’m not disappointed! Makes me want to buy a bigger Tungsten cube but wow they get expensive fast! This is the perfect inexpensive way to experience the wonder that is the TUNGSTEN CUBE. All other metals feel like nothing compared to this incredible element. You must experience the power and wonder that is the TUNGSTEN CUBE! Bow down to the density! Also it has cured my mortality!

They’re smaller than I thought but really makes you think of molecules and molecular structures. They’re a definite conversation piece.

Shape: Very square, to the point that the corners and edges are a bit sharp (though not dangerously so). Weight: The magnesium cube is extremely light for its size. The tungsten variant seems too heavy to exist relative to its size. Put another way, if you drop the magnesium on your foot a corner might scratch you, whereas the tungsten cube will probably break your foot Finish: Both have a brushed finish with laser engraving Quality: Both seem literally solid, no obvious imperfections Like I said: Metal cube. Almost the simplest possible object. Very cool for display, and the tungsten cube makes for an interesting paperweight.

I love these cubes.

I’m not sure what I was expecting but the cubes are exactly 1 square centimeter (10mm) on each side. I got exactly the ones from the store image (no extra Pb cube) and they are all lustrous (except for Carbon, not a metal) and machined to true dimensions. Good craftsmanship! Must be done by CNC adapter since this work is quite difficult by DRO. In any case, they arrived protected by 2 resealable plastic baggies and some plastic microwave wrap. No visible shipping damage on any of them as viewed by magnifying glass. The plastic storage box and the color periodic table are a nice touch. I’d buy ‘em again at this price (60) or hopefully at a discount. ;)
