Thank you for looking! ⑅︎◡̈︎* Please be sure to read my profile. This is a 24cm cocktail size, made in Finland. As it is an older item, I believe it is likely two layers. I stored it carefully in a clothing case with a desiccant, in a place away from direct sunlight. It is new and unopened, but please understand that it has been stored at home and is vintage. Thank you. Nordic, Decoupage, Cartonnage
