Like all Made Solid leather pieces, this one is cut, shaped, sewn and finished by hand in artist Peter Maxwell's Los Angeles studio.
"Using vintage leatherworking tools and traditional saddle-stitching techniques, Maxwell aims to create beautiful designs that embody both simplicity and functionality, and that develop rich character and patina over time."
Understandably, the item - available at Nordstrom since November 18 - has left many shoppers confused.
Made Solid, the company which designs the leather/rock combo, told BuzzFeed News it was "one of our most consistently popular items, actually" and insisted "it's not a joke."
The company described the product as "really cool, labour-intensive objects that are used as everything from paperweights to doorstops to home/display accents."
