Brass and leather, crafted in Japan
These keychains are made in Japan from solid brass and cowhide leather. Their design is inspired by the room keys of an imaginary hotel, with a simple look that is instantly recognizable. The brass develops a natural patina with use, while the leather retains the marks of hands and pockets. The two materials age at different rates, so each piece eventually comes to reflect the person who carries it.





THE PICUS EXPERTISE
What makes these keychains unique
Solid brass and leather
These keychains combine a solid brass piece with cowhide leather. Two rich materials, assembled in Japan.
A drawing of a room key
The shape takes after the keys of an imaginary hotel. The style remains simple, with an organic appearance that improves over time.
Patina, the signature of time
Brass naturally darkens with use. Two identical pieces at the start will always end up looking different.
An object that can be worn
It lives in a pocket, a bag, a hand, rather than resting on a piece of furniture. It's this daily handling that makes it evolve.
The spirit of travel from days gone by
PICUS captures the imagination of travel from the past, with trains and grand hotels, their numbered keys, and luggage tags.
Two materials, two interviews
Brass can be polished to restore its shine or allowed to darken naturally. Leather, on the other hand, should be kept dry and away from prolonged moisture.
