Mechanically exfoliated graphene (obtained with the famous “scotch tape” technique) comes in small, high-quality flakes. Exfoliated graphene has so far shown to hold the best physical properties, reaching towards theoretically predicted current conduction, mechanical strength, etc. The coverage of mechanically exfoliated graphene, however, is only on the order of a few small flakes per square centimeter, not nearly enough for applications. In addition, the price of such graphene can be on the order of several thousand dollars per flake.

So doing the maths a few flakes will cost around 10 thousand dollars (probably US).

Once LWP starts licencing /producing this economically and in commercial quantities, they become the world supplier until other graphene-producing methods get commercialized that can compete with them.
