100PCS Metal Keyring Blanks Split 25mm Sliver Key Chain Rings Kit for Home Car Keychains, Lanyards, Gifts and Other Crafts Jewelry Making,Keyring Rings

These are great quality, I've been using them to make custom key-chains, and I'm happy with their strength and durability for this. The O ring (which you attack to the items, not the key part) is 1.2mm thickness, around 8mm in diameter. The only slight negative is that the aforementioned O ring isn't always completely flat, but there may be a slight kink in it - which matters a little when I've 3D printing things to fit it exactly, but it's also easily resolved by squashing it flat with some pliers. But if you're not into 0.1mm accuracy, then it'll be fine for you. It's really a very minor point.

Good sturdy keyrings for various designs of your choice.

Good quality and very good value.

These are good quality and a good price, but there’s definitely not 100 in the pack. Ordered two packs, 187 needed for PTA project and I’ve run out. Decent product but I’d over order if you need a certain amount

All delivered on time and fit for purpose - Thank you

Perfectly adequate.

Quality is not the best think small rings are not strong enough

Great product, good quality, would use again.

انا طلبت نفس المنتج اكتر من ٣ مرات الخامة حلوة بس مرة العدد بيبقي اقل ومرة يبقي مظبوط بس في كام واحدة بايظين بس في المجمل المنتج حلو

The rings are tiny, it's not the standard diameter, and the thickness of the ring is very small and fragile.
