80s retro belted napkin rings set, gold tone metal belt and buckle

'Belted' style napkin rings, cast metal with gold tone finish. These are 80s vintage, I think? They're made all as one piece (not buckling and unbuckling). We didn't find any markings at all.

It's a set of eight napkin rings, most in excellent condition. A couple have a little light wear to the gold finish.
