The Master-Piece Carabiner Keyring is a functional everyday key holder designed for smooth, secure carrying on a belt loop or bag. Part of the Master-Piece “Carabiner” series, it is ideal for commuting, travelling and active daily use, combining practical utility with a striking black and gold finish.
Made in Japan, the keyring features an original carabiner paired with high-quality North American steerhide leather. The leather is tanned using 100% vegetable tannins without chrome, creating an eco-conscious finish that preserves the natural character of the hide. Solid brass double rings and hardware give the piece weight and durability, while engraved Master-Piece detailing, three key rings and a removable hook add considered functionality.

Master-Piece, also stylised as MSPC, was founded in Osaka, Japan in 1994 by Taichi Fujimatsu. Created with the purpose of making bags for everyday life, the brand helped define the modern “city bag” by combining practical function, durable construction and a refined urban look. Rather than treating bags as purely technical or purely fashion-led, Master-Piece brings the two together, creating pieces that feel considered, useful and distinctly Japanese in their attention to detail.
A key part of the brand’s identity is its use of high-performance materials and carefully developed components. Working with domestic and international suppliers, Master-Piece creates original fabrics and hardware designed to improve strength, comfort and usability. In 2008, the brand established its own Base Osaka factory, allowing it to maintain a close connection to production and ensure the meticulous standards expected from Made in Japan craftsmanship.
What makes Master-Piece stand out is the way its bags reveal their quality through daily use. Every pocket, fabric choice, strap, zip and construction detail is designed with purpose, offering a balance of technical function and understated style. Rooted in Osaka craft and built around functional beauty, Master-Piece creates dependable everyday bags made for modern life -practical, refined and quietly distinctive.
