I am selling perfect cubes. That is, blocks with H=L=W, all sides exactly identical. Assuming rock creation is completely random, they are depending on how you define min and max rock sizes between one per 150k to one per 250k. Quite rare in other words.
I currently have the following in stock:
Lightslate:
2.25: 300k
2.0: 250k
1.87: 225k
1.75: 200k
All my cubes are of course completely unprocessed and unchiseled. It's not possible to create perfect cubes from unrefined materials, since a chisel shrinks all sides equally.
I am open to negotiations.
