Pack of 3 - Sterling Silver Round 9.5mm diameter Filigree Box Safety Clasps, 2-Strand - New in bag

Pack of 3 Sterling Silver Round 9.5mm diameter Filigree Safety Clasps, 3-Strand, originally  available from Rio Grande as P/N 634157, new in bag.  The description Rio Grande uses is filigree and I'm afraid I can't really improve upon that description.  Images do a marginally adequate job of representing the lot.
