In addition to wood, Umage uses other durable materials. These include feathers. These are RDS-certified, which means that they come from 100 % sustainable and flawless production. These are goose feathers that would otherwise be burned and wasted. This reduces the environmental impact and ensures the welfare of the animals. High-quality metal is also used by Umage. With lights made of the sturdy material, you set modern accents in your home.
