Set of six acrylic napkin rings that can hold salt and pepper with small holes for shakers. Each side has a stopper for filling with either salt or pepper and three small holes. Very cool mod acrylic look! Heavy acrylic. I assume these are from the 1980s or '90s. Each measures approximately 2 3/8" x 2 1/4" x 1" deep. Great condition with no chips or cracks.
