Split Rings Nickel Free 10 Pack

Finally some split rings that don't leave green marks on my keys. The 15.88mm ones fit perfectly on my carabiner and open smoothly without snagging. Only wish they came in a larger pack for the price.

The 12.7mm rings are just the right size for my small notebook charms, and the matte silver finish looks clean. Really glad they’re nickel-free—no irritation on my earlobes when I use them as jewelry fasteners.

Snapped these onto my spare keyrings and the 0.5 inch size is perfect for keeping small keys together without bulk. The nickel-free plating was the selling point for me since my old rings left green marks on my fingers. Ten in a pack means I've got plenty of spares for case fasteners too.
