U.K.–based cosmetics company Lush has once again unleashed its limited-edition Shark Fin soap in benefit of ocean-conservation and shark-preservation efforts.

The vegan soap is crafted from Arame seaweed, exfoliating sea salt, and lime oil, and is decorated with a miniature paper shark fin. It retails for $5.95 in stores and online, while supplies last. One hundred percent of proceeds will go toward the Rob Stewart Foundation, a nonprofit established in 2017 following Canadian filmmaker and environmentalist Rob Stewart’s untimely death.

The funds will help the organization continue its work in environmental education and raising awareness of the world’s dwindling—and misunderstood—shark population. The nonprofit is also supporting the completion of Stewart's Sharkwater: Extinction, slated to be released on October 5.

The film is the sequel to the Toronto-born activist's award-winning doc Sharkwater, which he was working on when he went missing during a diving excursion in Florida’s Alligator Reef last year. His body was found three days later at a depth of 220 feet.

“Rob believed that it was everyone’s duty to protect our oceans,” Brandi Halls, director of brand communications at Lush, said in a news release. “By re-launching Shark Fin soap, supporting the foundation and continuing to engage our customers on ocean protection, we hope to help his vision live on for years to come.”

Lush’s Shark Fin soap was first released in 2014. Sales of the product in that year, 2015, and 2017 have raised over $700,000 for the cause, and generated strong support for the ban of the shark-fin trade in North America.
