You can get these in resin jewelry making kits. The gold leaf in those is super thin!

Not this thin, unless Chinese manufacturing has made heretofore unknown advances in materials science.

  You jest, but I wouldn't put it past cheap Chinese manufacturing to somehow do this at some point in the next 100 years. "How did you invent a room temperature supraconductor? -we thought it would save us $0.00001 per part"

    Eh, margins aren't that low on cheap Chinese gear with questionable IP rights. Not so low that they would develop an in house solution to a .02 cent market deficiency. I know you're jesting the jester, but Chinese manufacturing is on par with "the west" in terms of making money hand over fist on selling plastic junk, with minimal risk due to overpricing

If you can see or handle it, it's not a single atom thick.

  Graphene is definitely observable every time you use a pencil. It will mostly be graphite, but parts are graphene as well. And if that isn't enough, the tape method of producing graphene also makes a visible layer.

    Graphite, not graphene.

    I doubt you're ever seeing a single layer from a pencil. "Although graphene is probably produced every time one uses a pencil, it is extremely difficult to find small graphene crystallites in the “haystack” of millions of thicker graphitic flakes which appear during the cleavage. In fact, no modern visualization technique including atomic-force, scanning- tunneling, and electron microscopies is capable of finding graphene because of their extremely low throughput at the required atomic resolution or the absence of clear signatures distinguishing atomic monolayers from thicker flakes." -- Making Graphene Visible https://www.physics.purdue.edu/quantum/files/CarbonNano/make-graphene-visible.pdf https://www.physics.purdue.edu/quantum/files/CarbonNano/make..., which shows it can be made visible by preparing it on an appropriate substrate.

    Not true.

  Says you! Some of us have the skills required to handle a .0000003mm mechanical pencil. In 2B even!

    Interesting, but that sounds like it's in the realm of tools, not direct handling. Either a normal sized pencil that contains that thickness of material, or a microscopic pencil that itself needs tools to be manipulated.
