    I like the size, and weight of this cube. I have to agree with others the dimensions result in sharp crisp edges, don't drop this on bare feet or open toes.

    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.

    This was the most expensive element cube I bought, but it is by far my favorite to hold and play with. The machining is so precise. Edges and corners are sharp and exact.

    1.0 out of 5 stars Element Name is Wrong
    Reviewed in the United States on November 26, 2024
    Either I did not get pure carbon or this is misidentified. The element name is Carbon. Graphite would be a phase of pure carbon. This "element" cube is identified as "Carbonium". Carbonium refers to an ionization of carbon within organic compounds. The purity stated is 99.95%. I had seen some cubes of carbonium and I had specifically clicked on one called Carbon.
