Inception by Accel Company "violin F-Hole" Key Holder (IPK-02)

Size Guide
A functional piece to showcase exquisite Japanese craftsmanship!

Accel company has designed a beautiful carabiner key holder, inspired by the characteristic 'F-shape' sound holes on violins and other classical string instruments.

The solid brass carabiner has been created using a method called "lost wax" casting, in which the metal cast is based on an initial wax prototype. This allows for more complicated and beautiful designs to be created compared to using regular casting methods!

The heavy-duty brass linked chain and key ring ensure this piece will remain durable for many years to come!

If you are looking for a heavy-duty, functional key holder with an intricate design then this could be a perfect choice!
