Key Ring Keychain Assorted in 4 Sizes Metal Round Split Key Chains Rings for Home Car Dog Tag Office Lanyards Keys Attachment Black Pack of 40pcs

So many sizes to choose from. Perfect

This assorted set of silver key rings is really useful if you do any kind of crafting, jewelry making, or keychain projects. The metal feels sturdy and holds its shape well — not flimsy or easy to bend like some cheaper sets. The finish is smooth and consistent, giving everything a clean, polished look. The four different sizes are a big plus. It makes it easy to match the right ring to the right project, whether you’re making charms, bag accessories, lanyards, or full keychains. The rings open and close smoothly without gaps, so items stay securely attached. If you want a reliable, versatile set of key rings that works for all kinds of DIY projects, this assortment is a great value and very convenient to have on hand.

These rings seem to be a decent quality and are easy to use in your specific project. I used them with para-cord to make a hand-held key-chain as well as a neck-lanyard key-chain. Works great so far and the (anodizing) finish seems to hold up well.

These fit the bill and are great quality. They also have a weird coating that smells, assuming it's a protective lubricant

excellent quality and value for money
