A Magnetic modular Key Holder. Each Module holds 5 cards and they are keyed so that they can be aligned vertically.
Initially designed for the audio card for a Yoto Player but by Happy coincidence the cards have the same dimensions as a standard Credit/Debit card, Library Card, Oyster Card, Driver License etc.
Each module requires x2 5mm x 1.5mm magnet.
The author marked this model as their own original creation.
