I wanted to further lighten the load I carry. So, I reduced the number of keys I had on my keychain (to the ones I use daily). Afterwards, I wondered how else I could make it lighter. And when I saw this, “Wow, no keychain!” This is just what I need. So minimalist! :) -Danny ‘While you sleep’ is a system that groups keys together using a clipping mechanism.
