► BIODEGRADABLE PHONE CASES FOR DIVERS
WoolFin creates biodegradable wool phone cases that dissolve underwater into fish-friendly nutrient pellets—while you sketch the marine life you encounter. Every dive becomes a conservation act.
Start Your Journey► THE WOW MOMENT
"You're 20 feet underwater, surrounded by colorful fish, watching your wool phonecase slowly dissolve into tiny pellets that the fish actually eat—while you tap your screen to sketch a clownfish you just spotted, adding it to your growing underwater life list that other divers can see and contribute to."
Each wool case gradually breaks down in water, releasing nutrient-rich pellets that fish actually consume—zero waste, full circle.
Temporary water-repellent coating keeps your phone dry during dives, even as the outer wool begins its transformation.
Digitally pencil-sketch every fish species you encounter. Build your personal catalog of underwater life, shared with a global community.
Every sighting contributes to marine biology research. Your sketches help scientists track fish populations and reef health.
