DGOL100pcs 1 inch (25mm) 304 Stainless Steel Keychain Hooks Chain Cord Flat Orgnize Key Rings Webbing Wire Keyring Hook Clasp

I'll keep this short and sweet. I'm SUPER picky about my things and value QUALITY.These are NOT every other El Cheapo split ring available on Amazon with the snaggy sharp cut ends.DGOL split rings are: STURDY Sanded SMOOTH ends. ZERO jagged edgesDOWNSIDES: So strong they are slightly hard to open

Used them to fix luggage zipper pulls - worked great.

I purchased these key rings to make homemade key rings (with chain and pendants). My initial thought opening the package is that THESE ARE SMALL!! But that is exactly what I wanted for the project I was working on, so it worked out perfectly for me. :) I just didn't expect them to be *quite so small.* However, I was pleased with this, so it worked perfectly for my needs.I am not deducting an overall star for this (just on the "easy to use" category); however, the key rings were very difficult to pry open by hand. I was only stringing link rings to connect the chain to (not onto keys), but I am certain stringing keys onto them would present the same level of difficulty. If these are to be used for key rings, be at the ready with the appropriate tools to pry them apart without using your fingers or nails. In my opinion, these would best be used for a purchase where they are not going to be opened frequently (and will keep your keys safe for decades, I'm sure).Overall, I am beyond pleased with how my project turned out, and the smaller size worked incredibly well for me. Please see photo with ruler for size reference (the pendant/button is between 16-19 mm, which is about 3/4 of an inch).I would absolutely purchase again, as these are a quality item (even with the difficulty I experienced prying them open).

Good quality. Great for better securing your keys over the standard split rings. They are harder to work with, but once keys are on, they are secure.

These split rings are beefy and tough. Didn’t really work well with the dog collar ring, because they would open up enough to go on.

Using .06 inch rings - These would be great for lots of things, but of course my application finds a flaw…The good:These are very strong, much stronger than typical round wire rings.Cut/open ends are much smoother than standard rings. Less snags on clothes/gear.The bad:Not as much return spring as I would like. Opening more than 1/8 inch to attach causes permanent bend. I’m sure a larger dia. ring would not have this issue as much, but would be too big for my project. I plan on buying larger versions for other projects as the overall design is really good.

Worked as expected.

There are sharp ends on the split rings that interfere with using them. I assume it's where the wire was cut before bending it into a ring. You might look at a different brand if you need split rings.
