I bought the matching ball chain for these connectors, and it was a bit difficult to get the ball chain into the connector at first. However, after I got it in and connected it stayed put.

I do leather crafting and supply's can get expensive from the leather craft stores. I needed something smaller than the larger size ball chain closure's they offer at the stores. These (along with the chain) fit my needs perfectly. I tested them out with a good snap/pull on length of chain and they didn't bend or break. These would be good for lighter weight stainless steel pendants as well without the bulk of larger size. More feminine sort of speak. If you are in need of a smaller size closure, look no farther then these. These are a great value, strong and look good as well. And like myself, they can be used for just more than jewelry. I highly recommend, especially at such a great price. Thank You JewelrySupply.com, I'll be back for more when the time comes.

very strong

Exactly what I was hoping for!

These connectors are surprisingly very sturdy. Although they ended up not being the connectors that I needed for my particular project, I still recommend them as they hold up quite well!

These are awesome quality and fit the 1.5mm diamond ball chain perfectly! Sturdy and color match is good!
