For years, item tracking has relied on disposable or lithium-ion batteries - adding waste to our environment.
Nimble and Flint are changing that by integrating ultra-thin, biodegradable paper batteries into travel essentials—creating a new category of accessories that are trackable, rechargeable, and radically responsible.
Visionary Partners
Flint is a deep tech company pioneering sustainable battery technologies from the ground up, rethinking how energy storage is designed, manufactured, and used. By combining cellulose-based materials with manufacturing-ready processes, Flint creates batteries that prioritize safety, scalability, and lower environmental impact.
Paper is the Power
At the core of every accessory is Flint’s breakthrough paper battery, developed for a more circular energy solution.
Biodegradable by Design
Cellulose-based materials and non-toxic, water-based electrolytes dramatically reduce environmental impact at the end of life.
Razor-Thin Integration
Less than 1mm thick, the battery is embedded directly into the product–preserving the slim profiles required for modern travel.
Recharge, Don’t Replace
Wireless charging compatibility means power can be restored again and again, extending product lifespan while eliminating single-use battery waste.
Globally Trackable, Thoughtfully Powered
Each accessory connects seamlessly to the Apple Find My network, so you can locate your essentials anywhere in the world using the Apple Find My app. It’s peace of mind travelers expect–powered by technology the planet can live with.
Travel Essentials, Reinvented
The initial collection includes: luggage tags, keychains, slim wallets, and passport folios. Each piece is crafted from Nimble’s cruelty-free plant leather and post-consumer materials–designed to move with you, not weigh you down.
