And this:

"In order to produce the highest quality graphene, the only way of achieving this is to use higher quality starting materials. Our graphite undergoes no chemical and physical engineering changes to improve quality. Straight from the ore the purities range from 80% - 99.76%+ (highest purity level recorded), the most important fact is that the graphite has very little impurities, allowing successful integration into your final applications."

Sounds a little familiar...
