Soft Italian leather cradles your Apple AirTag. These are hand cut, hand sewn and finished so each product has character you won’t find in mass produced products from a factory. Each AirTag holder has a water resistant finish applied. It will hold up to outdoor activities like being attached to your child’s backpack, but I don’t recommend attaching them to scuba gear while you’re exploring Caribbean reefs. You can definitely stash it inside your dive bag to track your luggage on your way to and from exotic destinations. These are also great for tracking more mundane items like the forever misplaced car keys. If you need nickel free hardware, please message me for availability prior to placing your order.
