Edelweiss Pattern Height: 2.5 cm Diameter: 2.3 cm A sticker is affixed inside. Swiss National Pattern Height: 2.8 cm Diameter: 2.3 cm Pottery? Plastic? I believe it's pottery. The Swiss pattern came in a case, but the sponge deteriorated, so I've replaced it with cotton this time. No stains or scratches are visible. Although unused, these items have been stored at home, so please refrain from purchasing if you are concerned. Thank you.
