This is a lovely set of vintage 1930s napkin rings.
I think that they are Bakelite rather than being a later Catalin plastic.
As you can see from my photographs - these are a set of four rings, and all the colours are quite muted tones - or butterscotch (like caramel), a mottled dark tangerine, a slightly paler butterscotch and and darker chocolate brown colour.
All the rings are in good condition - as shown. No chips or damages and the finish is nice and shiny.
Each ring measures as follows: 4.5 cm (measures to the outer edges) and each ring is just about 1 cm in height.
A fine little group of four Art Deco rings.
