At first glance there doesn't seem to be anything remarkable about these cubes. But when you pick them up they feel so light that your brain does a bit of a double take - especially if you've been handling other metal cubes just before! Ordinary graphite is quite cheap but while visually identical we specifically sourced the highest grade that was available, 99.99%, just because we all want it to be a little less ordinary, right? And there was not a significant bump in the cost which is always a nice bonus. Weight is 1.8±0.1g.
