Hey crafty people, I've got a problem. I have a set of lanyards I use(d to use) regularly with art I really enjoy, but the lobster clasps (similar to below picture) have broken over time from the lanyard getting caught on stuff as I walk around. Are there sturdier or "heavy duty" clasps out there I could get to replace them? I'd rather not keep a stash of cheap and non-durable clasps around to keep replacing if I can avoid it.
