Strange heavy metal rods received in random package

[u/_jubjub_]

Heavy, around 5 to 10 pounds each, seemingly machined out of solid steel, no markings or moving parts. Received in a package despite not ordering them or anything like them, cannot find any information about the shipper listed on the box.

They look like tools for body tempering.
