Tesla isn’t just a car company anymore. They’ve moved into the surfboard industry as well.

Over the weekend, Tesla released a line of custom surfboards built in collaboration with Matt “Mayhem” Biolos and Lost Surfboards. The boards are made out of reinforced carbon fiber and feature a a combination of finishes found on their cars. The boards were also designed to fit perfectly inside Tesla’s Model S, X and 3 cars.

The surfboards sold out in a just a day but they’re available for purchase on eBay now.
