The Oiva tea set is made of brown stoneware & it features the Seireeni pattern. The teapot has a ceramic strainer and a wooden handle and peg on the lid. We recommend washing the teapot by hand. While traveling in Greece in the early 1960s, Maija Isola got inspired by the movement of water and depicted it in several fabric prints, including Seireeni (siren) from 1964. Named after the mythological sirens, the pattern also recalls the enchanting singing that lured sailors into dangerous waters.
