## Description and construction

Sometimes you just need to switch things up, whether it’s the webbing on a handbag or a decorative charm. The Circular spring clip lets you do exactly that. Just snap it open, swap things around, snap it shut. No permanent connections, no drama.

Saves time during assembly and repairs: when your customer wants a new Webbing color, the swap takes just seconds.
Flexibility for your ideas: changing decorations, adding charms, or testing new versions of a single model? Just snap!

There’s a catch, though. It’s not a heavy-duty hero. If you need something for hauling serious weight, go for a solid welded ring or a carabiner instead. And heads up: the ring needs to be closed properly, otherwise it can damage a leather loop or come undone on its own. Always double-check it’s shut.


## Limits and maintenance

* Handles typical outdoor conditions without issue — rain, mud, moisture, sweat. No need to dry or treat specially after every water contact.
* Reliably protects the underlying material during typical outdoor use — rain, dew, occasional wetting. May not be sufficient for permanently wet environments.
* Handles normal everyday wear. At exposed points — where regular friction or contact with other metals occurs — traces of wear may appear over time.
* Over time loses its original gloss and the tone changes slightly. This does not affect function, but the surface eventually does not look as fresh as at the start.
