The listing, Split Rings has ended.
These are those rings that you put your keys on. Split in the middle so you can work your keys onto them. Only they're small, 1/2" in diameter. I use one to keep all my discount cards on. You know, Kroger, Petco, CVS, Ace Hardware, etc. That way they're not overloading my key ring & I keep them in a side pocket of my purse.
