They're call pure THC Crystal Cubes... obviously this is well possible, i have bought THC crystal before and had alot of fun.
He claims they will cost me $20 a gram. He has proven to be nothing but a reliable dealer, I'm just checking with the GC community in case this is a possible rip-off. I'm just curious because i've never heard of them before now.
And if it's as strong as crystal then it's well worth the $20.
