Lot of old-fashioned metal curtain rings - gold toned aluminum, or brass - non magnetic metal. These are used but all in good condition without a lot of spotting or wear.
There's 16 of the oval shaped rings, and 8 of the round rings. Ovals are 1 1/2" long x almost 3/4" wide over the oval openings, the rounds are 1" diameter over openings.
