Elon Musk’s flamethrower, branded and sold via The Boring Company, his new tunnel digging venture, is now all sold out. That means 20,000 buyers have secured pre-orders, and at $500 per, that adds up to $10 million in committed funds heading to The Boring Co’s coffers.

Musk started selling these via The Boring Company’s website just a few short days ago, on Saturday, January 27. He noted that 15,000 were sold just yesterday, and now the remaining 5,000 are all claimed, per a tweet from the serial founder.
