Nimble x Flint


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.
