– High quality (Swedish) vegetable tanned leather
– Brass trigger snap

Despite all the digital and technical 'advances', a set of keys is still a set of keys. We cannot live without them and keeping them close is essential. This sleek minimalistic leather key holder will do just that. The little button enables you to open the loop. This way you can wrap the strap around your belt and let the keys rest in your front or back pocket. The trigger snap is wide enough to carry a big set of keys. 

Functional and aesthetic: just how we like it!
