1 Pc Detachable Heavy Duty Dual Key Ring Safety Key Chain Pull Apart Snap Lock

I usually love having these for my keys, but the 1st one broke rather quickly, like within 2 weeks. I'm on my 2nd one, so far so good. Will update if it lasts.

It’s a good key chain but I thought it would open in the middle and it doesn’t. It just swivels.

Not at all the first time that it was out of my hands it breaks up in 4 pieces

These are great to add to key rings to be able to quickly disconnect a key.
