A key manufacturer feeding crypto’s twitter’s tungsten craze is auctioning off an NFT tied to the largest tungsten cube it’s ever made.

The NFT’s title says it all: “The Tungsten Cube – 14 inch, ~1,784 lb cube held in Willowbrook, Illinois, USA by Midwest Tungsten Service.” Bidding on OpenSea begins Friday, e-commerce director Sean Murray told coindesk.

According to the description on OpenSea, the NFT grants its holder once-a-year visiting rights for the super-dense cube.

The NFT is the latest twist in a week-long meme saga that turned a sleepy metals manufacturer into crypto twitter’s unlikely celebrity…. And all because of super-dense cubes

Traders and journalists and tweeters and moonbois have all been acquiring these desk tchotchkes for hundreds of dollars or more. (Full disclosure: this reporter has his own Midwest 1-incher. It’s surprisingly dense!)

Keeping the 14-inch cube at Midwest Tungsten HQ might be out of necessity.

Murray previously told CoinDesk that Midwest Tungsten was considering creating a supremely heavy cube but wasn’t sure how to get transportation squared away.

He’d also sworn to keep Midwest Tungsten focused on the metals and not NFTs. But a week of surging sales changed the calculus.

“I wanted to let you know first that we’re going to try an NFT. Swerving out of our lane, I guess. The crypto twitter community’s enthusiasm for cryptocurrency and NFTs is contagious.”
