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

1 inch cube, arrived safely and intact with only minor loss of sharpness in some corners due to being filed that way or transport trauma. Amazingly heavy. Very beautiful.

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.

I love these cubes.

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.

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.
