Keyrings with integrated magnets for EIGHT & BOB

The project

We manufactured keyrings for EIGHT & BOB with a function beyond holding keys: housing the magnet used to operate an opening and closing mechanism. The commission combines a two-piece construction with the brand’s logo engraved on the front.

Each keyring consists of two pieces of black acrylic, one 2 mm thick and the other 3 mm, bonded together. CO₂ laser cutting defines the outline and the keyring hole.

To accommodate the magnet, we recessed the back surface using multiple CO₂ laser passes at a higher power setting. The magnet that operates the opening and closing mechanism is inset into this recess.

After bonding the pieces and inserting the magnet, we engraved the EIGHT & BOB logo on the front with a fibre laser. The manufacturing process therefore combines two laser technologies with distinct roles: CO₂ for cutting and recessing the acrylic, and a fibre laser for engraving the brand.
