You can get these in resin jewelry making kits. The gold leaf in those is super thin!
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
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.
"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..., which shows it can be made visible by preparing it on an appropriate substrate.
