Although we do recommend a minimalist approach to key carrying, the Orbitkey can accommodate between 2 to 7 standard keys (each 2mm thick).
We have designed our universal locking mechanism to adjust depending on how many keys you have.
For a minimum of 2 keys, we would recommend using the 2 wave washers (that come with every Orbitkey) in the system. This will help keep your keys in place, and won't swing out. Click here for an illustration.
