KeyRing Locker® S-Biner® Plastic

I clip one of these to my belt loop and it holds three keys without any bulk in my pocket. The little lock tab actually keeps the gate shut, which my old carabiner never did. Five colors means I can grab the right set without looking.

The stainless steel ring feels solid in my hand, and the plastic clips snap shut with a satisfying click that holds my keys snugly. I’ve loaded three keys on one S-Biner and it hasn’t popped open once in my bag over the past week, which is more than I can say for my old keychain.

The color-coded S-Biner clips make sorting my keys actually painless, and each one holds three without feeling flimsy. I’ve clipped a whole set onto the steel ring and it stays shut tight even when I toss it in my bag.
