    5.0 out of 5 stars Very small

    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.

    I don't have the scales and beakers to test the claims for 99.999% pure. I sure like the comparison cubes. Sometimes it is hard to comprehend the density and weight differences of elements until you have a set like this. Highly recommend.

    this carbon cube is the coolest item to have, it lets you feel the material and the weight.

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

    These cubes are really cool all 15 of them order came fast also order was packed perfectly and with care. I messed up on ordering this I apparently ordered the tiny ones not the 1 inch I only put this in the review so others won't make the same mistake it's not the shippers fault I was going to took off a star because a few cubs had scratches over the information area but was still so happy with it I ordered the gallium metal I can clearly still see info no big deal.

    5.0 out of 5 stars It's a metal cube
    Reviewed in the United States on November 10, 2023
    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.
