Shagreen is a type of rough untanned skin made of the skins of sharks and rays (thanks Wikipedia!) It's typically used to cover anything from furniture, lighting, mirrors, accessories, or even walls! And here's a Fun Fact! because shagreen is typically made from the skin of sharks and rays, it’s impervious to stains and water. Perfect for nightstands, side tables and anywhere else you might pop a drink on. No need for coasters!
