The Terho Pendant Light is named for the Finnish word for acorn, a call-out to both the hallmark shape and the natural coloration of the fixture. Helsinki-based designer Maija Puoskari has created a union of uncommon subtlety—combining distinctively pale alder wood and opalescent mouth-blown glass. From Danish brand Mater, known for its eco-conscious ways, the Terho can be used individually or in groupings of different sizes for a refined lighting statement.
