Pastel polka dot napkin rings (set of 16) Savinio

Ceramic napkin rings. 4 of each color (pink, yellow, blue and green). Diameter/opening approx 1 and 3/4 inches and the rings are approx 1 and 3/4 inches tall. I'm not sure these have ever been used. Other than some very slight, unnoticeable chipping on a few (as pictured), these are flawless, in the same condition as when they were bought. Any slight marks are from manufacturing I believe. Absolutely beautiful set, high quality!
