This is a mushroom mycelium block breaker. I'm selling it because I don't use it as often anymore. There are many block breakers out there, but frankly, this one is different. The mesh is also quite sharp, so you can break down the mycelium block by its own weight, as if grating it. I think it was the best product of its time. I will also include a Cainz Hard Container 45. It can hold the equivalent of 6-8 mycelium blocks, and since it has a lid, you can break down the blocks and store them. Thank you.
